- Sharers, we'll need a lot of your help
because there seems to be more than one mystery neighbor.
- [Stephen] Yeah, in our backyard
it looked like there was at least two,
oh, there's John.
Hey, John!
- [John] Guys, I've got the GoPro.
- [Stephen] Oh, yeah.
You got it?
That's the one with the tracking device, GPS?
- I'm pretty sure I saw someone
coming out of the back alley
right behind the mystery neighbor house.
- [Stephen] Wait, what?
- We gotta hurry.
- [Stephen] What do you mean?
- Just come on.
We don't have time to discuss it.
- The back alleyway?
- Yeah, it looked like someone was coming out.
- Was it the mystery neighbor?
- I don't know.
I saw the garage door opening or something.
- Wait, there's a garage door back there?
- Yeah, remember, in the back alley.
- Oh, that's right.
We've learned that the mystery neighbor
goes in and out through the back alleyway.
Every house in Beverly Hills has an alleyway
and it looks like that's where the mystery neighbor's
been coming out from.
Oh, is that, hold on.
Whoa, whoa, whoa.
Wait, whoa, whoa.
Who is that?
(Stephen gasps) (Grace gasps)
- [John] No way.
- [Stephen] Oh, my gosh, that's the mystery neighbor!
That's the mystery neighbor.
- [Grace] Wait, where are they going?
- [Stephen] Where's she going?
- [Grace] To the right!
- Okay.
Guys, good news is that's the mystery neighbor,
bad news is we're on foot and she's in a car.
- And a fast car, too.
That's a Mustang.
- That's a Mustang.
Okay, we gotta get going.
Let's start moving on foot.
We gotta go,
but don't go too fast
because we don't wanna lose track of her.
Check it out,
that's the garage she came out of back there.
Okay, that's how she's been getting
in and out of her house.
So it's not the front door.
It's not the front door.
Let's go, there she is.
She's up the block.
There she is.
Guys, she's getting away.
She's getting away, she's going fast in that thing.
Go John, come on!
Gotta catch her.
That's definitely the mystery neighbor, though.
Hold on, hold up.
- [Grace] She's turning.
- She's turning.
Why is she turning?
No one turns up there.
That's kind of weird.
She might have noticed us trailing her,
so we gotta be careful.
We gotta be careful. - Stay quiet.
- I feel like she might be right around this bend up here.
We gotta be super careful.
Let's just see.
You ready?
Three, two, one.
- [John] Anything?
- [Stephen] Oh, whoa, whoa, whoa.
- Oh, she's outta the car.
- [John] She's outta the car.
- [Stephen] She's outta the car.
Hang on.
(intense music)
She's opening the trunk.
- Wait, what is she looking for?
- I don't know.
Sharers, comment down below what you think she's doing.
It looks like her car broke down.
- Oh.
- [Stephen] She's fixing something on the car.
She's looking at the tire.
- [Grace] Maybe she's trying to jump start the car.
- [Stephen] I think something's broken on her car.
- [John] Wait, Stephen.
- What? - This might be our chance
to get closer and stick the tracking device on.
- Oh yeah.
If she goes to the front of the car again,
John, take this GoPro, turn it on,
and stick it on her car.
And it's got the suction cup on it, right?
- Yeah.
- Okay, suction it onto her car, get it recording,
and then if she gets the car fixed,
we'll be able to track her
and figure out from video surveillance
who she is and what she's doing
and where she's going. - And where she's going.
- [Grace] She's on the phone.
- [Stephen] She's on the phone.
John, now's your chance if you go quick.
Do it.
Right, she's turning around.
Now's your chance, John.
Go for it, go.
- [Grace] Be quiet, be quiet.
- [Stephen] Come on, John, go, go, go.
Shh, quiet, quiet.
Come on, John.
Quiet, quiet, quiet.
Stick it on.
Come on.
Stick it on, stick it on.
John, get down!
John, get down, down, down!
I'll give you the signal when to get back up.
All right, go, go, go.
Back up.
There you go, hit record.
Come on, go, go, go.
Yes, yes, you got it.
- [Grace] She's about to turn!
- [Stephen] Okay, go, go, you're good, you're good.
Okay, we made it.
John.
- Did pretty good.
- Good news, we got the tracking device on.
- Yeah, did it stick? - We're good to go.
Did it stick, you think?
- Yeah, it's perfect.
- And you recorded it?
- It'll stay on and it's recording.
- Okay, it looks like she's getting ready to go, guys.
Bring out your iPhone, start tracking that GoPro.
- Okay.
- She's about to hop in and go.
She's hopping in, she's about to take off.
John, now would be a really good time
to tell me that your tracking device is working.
- It's loading, Stephen.
- Okay, well hurry up and load that thing
because she's about to take off.
Car's on, car is definitely on.
Tell me the tracking device is working,
tell me the tracking device is working.
Is it loaded? - No, it's still.
- Come on, John.
She's pulling away, she's pulling away.
It's working?
- [John] Wait, look.
It's synced, we're all good.
- [Grace] Okay, good, good.
- [Stephen] Let's get going.
There she goes, okay.
John, tell me where she's going.
- Going down Roxbury towards Santa Monica Boulevard.
Come on.
- [Stephen] Okay, let's go.
If we walk fast enough, we'll go.
She's gone, guys, she peeled off quick.
- [Grace] Yeah, she drives fast.
- John, keep that tracking device open.
Keep the tracking device open.
We gotta figure out exactly where she's going.
- She's going down Roxbury,
but then she's gonna make a right onto Santa Monica.
- Onto Santa Monica?
Okay, that's right up here.
If we turn right here,
we can make a shortcut.
- That's right towards the City Hall.
- Wait, the City Hall.
- [John] Remember the Uber?
- Yeah. - The Tesla Uber.
- Okay, guys, she's probably heading
towards the City Hall.
- I wonder what she's doing?
- Okay, nevermind, we'll make a left up here.
Come on, guys, go.
We can beat her here.
Grace, come on, hurry.
There it is, City Hall, right up here.
Right behind those buildings.
Let's get going, come on.
Go quicker, let's go.
Grace, come on, come on.
- [Grace] I'm coming, I'm coming!
- Let's go, let's go!
Here we are, City Hall.
She should be here any moment.
Keep an eye out for a blue Mustang Convertible.
Blue Mustang Convertible.
Get ready to hide, though, get ready to hide.
John, you see anything?
- No.
- [Stephen] You see anything?
- No, not yet.
- [Stephen] Okay, just keep your eyes out.
She could be coming from any direction.
- She looks like she's coming from the left.
- [Grace] Okay.
- She'll be here, oh, wait, there she is.
- [Stephen] There she is, there she is, there she is.
Oh, she's coming.
Get ready, hide, hide.
- [Grace] Hide behind the wall.
- [Stephen] Quick down, down, down.
Get down, get down, get down.
There she is, there she is, there she is.
- [Grace] There she is.
- [Stephen] There she is.
Guys, she's coming to City Hall.
She's totally turning in.
There she is, there she is.
- [Grace] GoPro's still on, too.
- [Stephen] The GoPro's still on.
She's heading down to the parking garage.
Guys, she's heading down.
She's going down to the parking garage.
- [John] We need to go down a different way.
- There's gotta be an elevator.
Elevator over here.
Sharers, this is the parking garage
that we were at last time.
Remember, we picked her up
in the undercover mystery Uber.
- [John] Yeah.
- Okay, she's definitely heading back
to the same parking garage.
The question is, what is she doing here,
why didn't she take an Uber this time,
and three, where did she get this car from?
- [John] Yeah, seriously, though.
- Okay, there should be an elevator right in here.
We'll take it down.
We'll meet her at the parking garage.
Let's go in here.
Guys, come on.
Elevator.
Okay, parking garage.
Come on, come on, come on.
Call that elevator.
(elevator rings)
Here we go.
Quick, go in, go in.
P1, P1, P1.
- [John] Close the door, close the door.
- Guys, we gotta be careful
because as soon as the elevator doors open,
it's gonna put us into the parking garage.
- We won't know where we'll be either,
so we're gonna need to hide right away.
- Okay.
- [Grace] Went down.
- P1, careful.
(intense music)
Okay.
Keep an eye out for that blue Mustang.
She could be anywhere.
- [Grace] She came in down that ramp.
- She came down that ramp.
She could be anywhere in here.
Sharers, keep your eyes peeled for that blue Mustang.
She could be anywhere.
Do you see her anywhere?
- No.
- [Stephen] This is a bigger parking garage
than I expected.
- She must have parked somewhere,
but there's so many parking spots.
- [Stephen] Okay, we gotta find,
there's a orange Mustang.
It's not blue.
Wait,
car up there, that's a Mercedes.
Wait, come on,
how hard is it to find an old blue car?
- Parking lots are so easy to get lost in.
- [Stephen] Come on, it's not that big.
I think we might have lost her.
Oh, whoa, whoa, whoa, whoa.
Bingo, we found her.
- Wait, she looks like she's waiting for someone.
- Yeah, because she's not in a parking spot.
- [Stephen] Wait, she's being an Uber driver for the day.
She's on the phone with someone.
Take a look at this.
Guys, she's waiting for somebody.
- Yeah, I wonder who. - Wait, what is she doing?
- [Stephen] I don't know who she's waiting for,
but she's definitely waiting for someone.
Remember, she went in there last time
to pick up the package?
- Oh, I wonder what she's doing this time.
- She could be waiting for another package.
We're gonna need to get a little bit closer.
I'm gonna try to go that pole right there.
- I'll go right here.
Stephen you go down there.
- [Stephen] Grace, you go to this one right here.
- Okay, perfect.
- [John] Ready?
- Three, two, one, go.
Go, John, go, go, go.
Go, go, quick.
Go, go, go.
Quick, quick, quick.
Okay.
I'm in position.
Sharers, comment down below
who you think she's waiting for?
She's waiting for maybe a mystery package delivery?
I have no idea what's going on.
Who is she waiting for?
- Wait, Stephen, look.
- What, (gasps) whoa, whoa, whoa.
Hold on, Sharers.
Things just got a lot more actiony.
- [Woman] So good to see you!
Long time no see!
- That's the mystery neighbor
and the mystery neighbor again.
I think there might be
mystery neighbor twins or something.
Hold on, what's going on?
What's going on?
They're putting something in the trunk.
(gasps) A mystery box.
Oh, my goodness.
Okay, hang tight.
- What is going on, you see that?
- [Stephen] I don't know what's going on.
- What is happening?
- There's two mystery neighbors.
I told you there were two mystery neighbors.
Hang on, they're getting back in the car.
Hang on, hang on.
Who's who?
Guys, who's who?
- I don't know, was there a package?
- [Stephen] They put a package in the car.
- [John] Have we seen both of them before?
- Hold on, John,
these are the two people
that were in the backyard sledding.
- Oh, you're totally right.
- There's two mystery neighbors.
The question is, who's who?
Who's the mystery neighbor?
- They almost looked.
Oh, their car broke down again.
- [Stephen] Sounds like it's just super old.
(car engine revs)
- [Grace] Oh, it started.
- [Stephen] It started.
They're about to take off, guys.
We're about to go on another high speed chase.
They're off, they're going.
Okay, the question is, where are they going?
John, is your GPS still working?
- Yeah, let me pull it out.
- [Stephen] We gotta track them.
Quick, John, what's your iPhone say?
- It looks like they're leaving.
We gotta go follow them.
- Let's go.
Sharers, we're on another high speed chase.
Gotta figure out where they're going.
My guess is they're going
back to the mystery neighbor's house.
- [Grace] Yeah.
- Let's go this way.
We're gonna have to make
shortcuts through the neighborhood.
Come on, let's go.
Okay, we gotta take the elevator back up.
That's the quickest way.
Grace, elevator back up.
There they go, there they go, there they go.
Okay, elevator, elevator, go quick, elevator.
Ground level, press that button.
Ground level, quick, come on, come on, come on.
- [John] Let's go, let's go.
- [Stephen] Hurry, hurry, they're gone.
- [John] They're leaving.
- [Stephen] Come on, here we go, come on.
Go, go, go.
Open, open, open.
Go, go, go.
Ground level, ground level.
- [John] Close the doors.
- Close the doors.
Come on, we gotta go, we gotta go.
High speed chase, we gotta make it back.
Here we go, we gotta make it back.
Sharers, who is this other mystery neighbor?
- I have no idea.
What are they doing, where are they going?
- I have no idea. - What's that package?
- There we go, come on, door open.
Open, open, let's go.
It can't be far.
Where did they go?
Let's go this way, back towards the neighborhood.
If we go back towards the neighborhood,
the house is here.
John, check the tracking device.
Keep tracking the device, we gotta find them.
Come on.
Where are they going?
- [John] Looks like they're nearby.
- [Stephen] Where?
- [John] I don't know, wait,
they just went right and then they went left.
- [Stephen] What street on they on right now?
- Bedford.
- Bedford, that's right up here.
It's right across the street here.
Okay, they're not far, guys.
Come on, cross the street.
Let's go.
- Wait, Stephen.
- [Stephen] What?
- Look, they're right there.
- Ah, they're there!
Quick, cut through the park, cut through the park.
We gotta beat them back.
This way, quick.
There they are, go, go, go.
Hide, hide behind the tree.
Hide behind the tree.
- [Grace] Oh, oh, there they are, there they are.
- [Stephen] Where?
There they go.
- [Grace] See them?
- [John] Wait, Stephen.
- [Stephen] They're not going that fast.
We can probably still beat them back to the house.
- Come on, let's go.
- Cut through the alleyway up here.
Make a sharp right, we'll cut through the alley.
Over here, go, this way.
Turn right after these bushes.
Three, two, one, turn right,
go, go, go, go.
There's the house.
Guys, we're gonna left down the alley,
that's where they're gonna be coming.
- [Grace] Alleyway's down to the left.
- [Stephen] Turn left, turn left.
Go, go, go.
There they go, there they go.
They're going back in.
Are they both in there?
- [Grace] Are they?
- They're both in there.
All right, they're going,
they're heading to the garage.
Let's go find out, come on, let's go.
To the garage.
Come on, guys, that's them.
The mystery neighbors are heading back
to the mystery neighbor house.
Okay, let's go find out what they're doing.
Let's see.
Uh oh.
- Wait, where'd they go?
- Hold on.
They might have already gone into the garage.
They already got in.
Guys, they already got in.
- [John] No way.
- [Stephen] Garage is closed.
- [Grace] So fast!
- [Stephen] They're in.
They're back in their house.
- Oh no.
- Well, the good news is
we know that the mystery neighbor
is back at her house,
the bad news is there's two mystery neighbors.
The question is, who are the mystery neighbors?
- Yeah. - That's what we need
to figure out. - Are they twins?
Are they sisters?
What is going on, Sharers?
Comment down below any clues that you know of.
We've got a lot going on here.
- Yeah. - We need to figure this out.
