While I do not have first-hand experience at Wake - my understanding is that under their particular brand of deferred recruitment - there is lots of opportunity to meet sorority women ahead of time. Girls are very hurt because they feel like they already have friends in their favorite chapter and might even pref there only to not receive a bid to their fave. This and the perceived tiers make it rough January.
Vandy is similar but not as bad
I just hate reading stories like this. Please encourage Rec Girl to give Theta a shot. I know how it feels like to go through deferred recruitment thinking you had made a friend in a particular chapter and then be cut by them. It just hurt like hell.
