Tonight the fifth season ofpremieres. It's a phenomenon among teens, but is also watched by a lot of adults. The spring finale earned a 1.3 adults 18-49 , up from a 1.2 for its premiere. Last summer, it premiered to a 1.3 adults 18-49 rating and ended its summer run with a 1.4 adults 18-49 rating. Given that the spring finale ended with some major revelations (Alison finally explained why she let everyone think she was dead for four years) and cliffhangers (Ezra got shot), can the ratings climb even higher tonight? Make your prediction!
