Seriously, I wonder if Emily was their answer for Georgina on
Gossip Girl. If they're going to keep bringing Jen back, I wish they'd have Emily return too. She was more fun IMO, though I know most of my fellow Lannie fans didn't think so.
Grimes and Cobb should re-enact the fights at the end of
Single White Female. That would be fun too.
