She's a Chi O and her boyfriend's a KA. They're listed on their chapters' web sites; it didn't take much snooping to turn them up! Her boyfriend's real name is James Jr., but apparently EVERYONE calls him Jimbo, because that's the name on his composite.
Someone else in the episode was wearing an "Owloween" shirt at one point.
Hottytoddy, you've GOT to dish us the dirt!
