I'm trying to point out that there are many plausible explanations that can be given for Hal's return to the Green Lantern Corps, more so than bringing Kyle; Parallax is just one possible explanation,. We don't know what the writers have planned. Maybe Hal isn't even a Green Lantern in story mode, only other game modes.back from the dead
Yes but I don't think Parallax is one of them. For one how would they have eradicated him from Hal's body or even know about the entity? In this Universe either Parallax and the events of Rebirth already happened meaning they can't be blamed for Hal's behavior or it's pre-Rebirth and Kyle never got a chance to tell people about Parallax. Maybe the Guardians do it, who knows, but it still begs the question of how Hal gets free of him without his soul being cleansed. If there's no outside influence then why the Guardians allow him to be a GL again is beyond me but, as you said, maybe he's not.
As far as resurrection we have The Joker in a leaked list and if that's proven true then why couldn't Kyle or anyone come back? If he's there during Flashbacks anyone is possible, if it's Scarecrow induced hallucinations then it makes more sense but I don't know if he'd be included as a playable character for such a bit part as that sounds more akin to the role Sindel and Rain played in MKX.
