Aiden was obviously a bellend, they just chose him because he's fantactic tele.
Josie is insecure, quite attractive, misses her family/friends from home, doesn't quite get that 'popularity' isn't such a big thing at uni and is gradually working it out. There are a thousand girls like her at any uni, she'll sort her confidence out and bag a mid 2.1.
Lauren I felt sorry for at furst, but her need for attention about the fact she was miserable was annoying.
The most uni moment I though was when Josie's flat were just chatting in the kitchen, she told them she had the clap and that guy wet himself and ran out to tell the rest of the block.
