No worries about the grads. The only exception would be Keiran, since he's the Headmaster and teaches Transfiguration. But he seems to be relatable to students mainly when they're in trouble, unfortunately. XD Even though he's my favorite besides Apollo (don't tell the others
-- and super don't tell Apollo
)
Apollo's definitely on the outs right now. Most of the students think he's either horrible (as in, he causes trouble all the time for no reason) or he's snooty. Partly because of the pureblood thing, I imagine, but also because he tends to keep to himself unless someone approaches him first. But that's mainly true because people think so poorly of him.
Christian's probably known as "the nice brother" between him and Apollo, but yeah, he's an easy one to plot with because Ace is so loud and he's always with her, and the PA thing. The students all definitely know that the PA is a thing, and may have even figured out who's leading it, but the joining process and where the meetings take place and whatnot are still secret. I'm 90% sure that they try to make it look like the meetings happen in other places, but they're held in the Room of Requirement. Once he joins he'll be able to access the hidden subforum there.
Ace asked Christian to help her lead the PA because he's considered more friendly than her, so even if Stephen got along well with Ace, he may choose to bring it up with Christian since he's less volatile. That's entirely up to you. Or we could have one or both of the Hufflepuffs talk to him about it. (They're kind of in a fight right now, IC, but we can play around with that depending on how Jackles feels.

Nicole is a darling, though she's oftentimes very misled. She's got a bit of a crush on Jonathan, though that hasn't fully developed considering she's still quite young. She just kind of likes that he's a bit odd like she is. So perhaps if Jonathan gets along with Stephen, and with Christian sort of stepping in as Jon's older brother figure, Nicole could wiggle into some of their plots now and then
