Interesting but i still think he isn't the bully. Looks like he wants to help her but only if she ask for it.
About his revenge, we don't know much yet but that was hella creepy to call all of the ppl and then tell that woman to say it was her. He is planning sth for sure.
Revenge on that black hair douche will be fun, i hope he already knows about his affair, still i want the girl to be "saved" since you can't chose ur parents.
