I'm afraid you've lost me already, kid -- or maybe I should say you lost me more.

[Beat.] Okay, let's take this from the top. You've been kidnapped to an alternate dimension by an AI -- artificial intelligence, basically a super-smart computer -- whose exact goals we haven't figured out yet. The bad news is that we haven't figured out how to send people home, either, not unless the Porter -- that's the AI --decides for herself it's time for someone to leave. The good news is that when you do get sent home you go back to the exact same moment you left, so you don't need to worry about your friends and family freaking out about where you are right now -- they don't even know you're gone.

The weird news is that once you get back you won't remember you were gone, either.

It's a little abstract, I know. With me so far?
