Cathy getting a gift she didn't want...which happened to be from Jen and me...at this point can tell because she has already given it back...and by the end of the party she had given the movie back to Jen saying she didn't want it because it wasn't aliens. "Aliens" meant that she was expecting Jen to give her the movie "Signs". As she told Jen she wanted that movie instead she made the motion of cutting off a finger like Mel Gibson does to the alien in the movie.
