Can you imagine James and Lily getting into a huge argument. Sirius and Remus are quietly watching. Peter is about to cry. Lily says maybe they should break up. James is distressed so he yells"YOU CAN'T BE SERIOUS!" And without missing a beat, Lily yells out
"OF COURSE I'M NOT SIRIUS! HE IS!"
A silence. James has no words. Remus and Sirius are astounded. Peter has passed out. This is the first time Lily has made a pun.
Sirius begins to slow clap, and Remus quickly joins in before falling to the ground from laughing to hard. James is still in shock and as Sirius pulse him back towards the castle he says "She's a Keeper."
