ELF: Well... what's the occasion? Why are we all conversing inside my head?
KEVYN: Petey has a way to patch missing parts of your memory with pieces of my own.
PETEY: I can synthesize experiences based on Kevyn's memories, or I can give you the experience of watching those memories as if they were a documentary.
ELF: Couldn't you also put Kevyn's memories straight into my head?
PETEY: I could. Subsequently observing and recording your descent into dementia would be very educational.
KEVYN: That's psycho-bear for "Can, but won't, thank-you-very-much."
