Haven't seen Supernatural but Traegert says the character is ace and that makes me feel the need to weigh in. It's not queerbaiting if the character they don't make gay after all is canonically ace. Putting them in a gay relationship would be ace erasure, and would be acebaiting. Sure, maybe it's gaybaiting, but revealing a gay-coded character is actually ace doesn't in any way diminish the amount of queer in the show.
