Colton?
You're alive.
I never thought I'd see you.
[EXHALES] I can't believe you're here!
Oh, I thought we lost you in the ***.
Who's that?
That's Sierra.
She's the one that got me here.
I'm thankful.
Did you tell anybody else about the tunnel?
No, just Sierra.
No one else is alive.
Your sister?
We waited as long as we could.
- You said you'd come back... - I'm sorry.
