Brooke and Lucas!! Always!! I love them SO much!! this can sound a little weird for you, but I still have hope they're gonna end up together! "People that are meant to be together always find their way in the end" and they are so meant to be.
The series isn't over yet... but I want to see the reunion of Puck and Rachel, I know it was just a fantasy and I really like Quinn/Puck... but Rachel/Puck just had some sort of of strange chemistry that I miss.
