I don't think he said mean things to her bc he didn't like her, more like he has this twisted obsession with her and she knew that and used it to her advantage. I think....
Well I think Dion wants to be hers and is obsessed with her so he had a totally perfect opportunity to make Roxanna oblige to take him and Roxanna accepted his offer saying she will take him as hers as she is gonna go to hell anyways and since Dion got what he wanted he did not chase Cassis, it was the part of deal na. I think that's it. I actually read a spoiler comment saying he wants to be her dog and wants to see everything she is capable of SEEMS LIKE HE IS A MASOCHIST FOR HER and I don't dislike it (⌒▽⌒)
OMG Wot? XDDDD How come I didn’t catch that!? I didn’t notice him trying to please Roxanna at all dafuq. I always thought that Roxanna is cautious of him, while he enjoys looking down at someone(Roxanna) struggling....just where did I miss!?!? _(´ཀ`」 ∠)_
Can anyone explain to me why Dion didn’t go after Cassis? Usually he’s so mean with Roxanna, but why did he suddenly listen to her and form alliance with her?? How did Roxanna even know that he’ll listen.....
