I think the most expected thing is that Malfoy is going to try and attack harry and then haryr's gonna beat him up and draco will team up with harry at the end, but that would be frankly, dissapointing. Hopefully, JK has come up with some totally unexpected plot twist that will shock us all, like, Draco ends up dying to protect harry cause he's always really been on his side but he was just holding up a mask to divert people. or something ^_^;;;
