"Come up with a way for other people to tell that they're really talking to you." My, Tim thought of that one quick, and he says it with almost zero hesitation. "Seriously, a lotta stuff here ends up...pretending to be you, or making you act like someone else." Sometimes literally.

"Come up with something - code word, signal, whatever. 'Cause I've been there, and it's not a fun place to be."
