Ian and Nina (Did this person just call Nina a bitch? At the end?) 

The person who called nina a bitch is a bitch cause nina is a nice sweet person and what did she ever do to that person uggh hate people like that!!!!

they're not calling her a bitch like that. they're saying it in the same way i'd call Nina a bitch...like "Nina gets to make out with Ian? =O bitch!" except they were talking about how she's naturally skinny.
