I really thought they'd end up together in the end, since their little dots of chemistry in the books which seemed to sound like they'd end up together. But of course, since Pansy represents one of j.k rowlings bullies, she didn't want her to end up happy, but it just seems random that he ends up with astoria greengrass. Theres no connection or any information on how they met etc.

To be honest, i thought Pansy would've been perfect for Draco...but thats just me because im a parkinson fan -don't hit me people!-
