Okay, uh. Chell looks no less confused, but somewhat less wary as she steps inside and pulls the door shut. Flipping to a clean page in her notebook, she writes:

I CAME OVER TO SEE IF ARTHUR IS OKAY
+ ASK SOME QUESTIONS
CAN YOU INTERPRET? TALK FOR ME?

"Interpret" might not be a concept the kid is familiar with, she figures. Well, wait.

WHAT ARE YOU IF YOU'RE NOT A TEENAGER??

She shows John what she's written -- then, loathe to leave Arthur out while John reads, passes the book to John entirely so she can use both hands to take one of Arthur's. U-O-K-? she writes in his palm.
