Personally, I'd like to see Conner get a corruption arc. He's the only one who hasn't yet. (I don't count the anti-steroids PSA arc in s1).
Has Artemis really had one? Also, can we agree that Kaldur's has been ongoing for two seasons and was never his undercover arc so much as his transition from treating members of the team as teammates and equals into treating them as agents (aka resources) to be managed?
From how I see it, and based on S3, Kaldur and Dick's corruption arcs have been an ongoing thing, with Kaldur having the potential to fall much further than Dick. Kaldur telling M'gann to mind-wipe everyone in S3 despite knowing the consequences to both the team and herself really cinched my suspicion that Greg is going to take that whole empathy gap (he has no empathy for himself and therefor has trouble extending it to those he's closest to. Love is for strangers! The trusted must be held accountable!) thing he has going to some dark places.
Also, he and Savage have had some interesting visual parallels that have my hackles up and ALSO have me reaching for popcorn. I've loved this man for over a third of my life, and I'm ready to watch him suffer if it means interesting character development. Or, if the whole Atlantis arc is just Kaldur learning to love and value himself that'd be cool too. If he can learn some empathy for himself maybe he'll be able to extend to others even after they get close to him.
BUT THAT'S NOT WHAT YOU ASKED ABOUT.
So, Conner. Conner is, I think, the most rock solid right now in terms of overall emotional and identity foundations. That or he's gotten superb at faking well-adjusted. But all that rage of his? Is it gone, or is it still under there? Is M'comm going to be enough to bring it back up to the surface?
The thing about Conner is that I don't know where his fault lines are. M'gann is very important to him, and most of his close relationships. But I don't think who he is would change or alter if they were threatened--he never stopped being the guy who will beat some ass when called for.
With Kaldur all you have to do is balance the cost versus benefit and he's down to do some really shady stuff. M'gann's self-image is key to her character, and that's been used against her really effectively. Dick is scared of basically everything these days (with good reason) so he'll do some wild, out-of-character shit to protect those closest to him.
But Conner? Artemis? IDK man. If you were writing it, where would you press down?
(Also I don't actually think that's fair to the Season 1 arc. The corruption was colluding with Luthor, a man responsible for his suffering, in order to get powers as a cheat code to self actualization. Trading the whole paragon of justice aspect of his ideal self for the physical powers. Not a great arc, maybe, but I think it was more complex than an anti-steroid PSA. Luthor was the moral compromise, not just the patches)
