Guys, give Whitely a break and the benefit of the doubt. Sure, it SEEMS LIKE he's a devious backstabbing spoiled brat, but minus the "backstabbing" part, Whitely is pretty much Weiss when we first saw her, with Weiss being far more crude than Whitely.



Oh I remember A LOT of people hating on Weiss in the beginning and I was quite annoyed at her too, though it was pretty obvious she was going to have some character development that would make her nicer. There's also Ironwood. So many people in the Rwby community didn't trust him then and thought him to be a possible enemy, but now it's established that he's probably one of the nicest person around even with his tactless actions.



We have to keep in mind that Whitely has probably less exposure to the outside word and thus would be more likely to believe whatever his father tells him, especially without a mother or sister to guide him towards the better light.



And for a big hint of Whitely not being happy about Weiss's punishment, look very carefully at his expression at 8:46 of RWBY Volume 4, Chapter 7(Punished).
