>>1194071To give LORE here, you're not entirely wrong, it's just that Winter's 100% in the right if he were to explode when they tell him what's really going down.
Trouble basically boils down to how they handled the BBEG. See, Winter just came from some real traumatic events around magic, where his brother has had some major identity crisis over it after spending years as another dragon thanks to a cursed amulet. Winter'd even put on that amulet himself, just to get a feel for what horror story his brother went through, so he has a first hand knowledge on just how bad that stuff is.
And yet, his friends, the 'found family' he traded his own for, the ones who he was going to return to from his old, abusive one, who literally tried to sacrifice him pitting him and his brother against one another, ended up being much the same. Saying when the BBEG put a spell on him that they PREFERRED him under that magic... Actually liked him better when he was enchanted.
Needless to say this put a pretty big spike on things. Especially when one of the friends was buddy-buddy with the BBEG, and the other was actively trying to hide information from that friend about how the BBEG was actively engaged in genocide the Icewings...
This all culminated with a later point when there's a big fight between the Icewings and the BBEG's army, and Winter goes off to help his family. Abusive though they might be, they were his family. Well, those 'friends' of his took this as some kind of shocking betrayal, for some unknown reason, and ultimately managed to trick the BBEG into enchanting himself using a scroll disguised as a strawberry.
Though that, too, has major problems, because they did this by turning him into a totally different dragonet, not even just deaging him but outright modifying his entire state of being, even going as far as to make him a hybrid Rainwing.
Needless to say, considering Winter has had personal experiences with that, he'd be unhappy.
And given his pretty strong moral codes, that even included saving Foeslayer, a legendary Nightwing villain by Icewing lore, because he found the punishment too far, it's very likely he'd have some strong words for the immorality of what they've done.
Ultimately he never returned to the school. He knows they're hiding stuff from him, and so, he chose to leave it behind, tragically blaming him
