Quinn Yanakakis

Quinn Yanakakis is the second to youngest sibling and the last Supplement in The Compound. He first appears at the end of chapter ten, when he wakes Eli up, freaks him out, and feels the need to take a shower. Later, Lexie holds Quinn and hands him to Eli when she needed to use the bathroom.

In The Fallout, Quinn turns one year old and has a penguin themed birthday party.
