I got a little mixed up about when you had to go on hiatus exactly, so I wasn't sure if Sam knew about Quinn and Puck getting back together.
Anyway, Sunshine would be happy to help cheer Sam up - in a purely G-rated, friendly way if that's how he would prefer it :) She's never had a boyfriend but has heard all about "rebound girls." (Hey, a basketball term! LOL)
Yes, Puck will glower and perhaps make sure he always plays against Sam in scrimmages....
(And I just thought about putting Sunshine's foster brother on the team, too, so she will hang around practice. She sort of follows the game anyway so it'll be fun for her.)
