I think the most interesting way Seawatt could come back into the narrative in a potential third parkour civilization movie is through the restoration of the fighter layer/ Seawatt’s old home.
A lot of Seawatt’s story is about losing control and trying to take it back so I think given the opportunity to take control in a healthy way and right the wrong that happened to his family + home layer could make for a really interesting story.
I’d imagine it would start off as an Emf/ Evbo adventure where they try to right the Old Man’s wrong but realize they’re in for a lot more than they bargained for. Since the layer was originally banished by a champion its going to take a champion to restore it to the regular order of layers. So Evbo coming into his godhood and Emf doing the same with his championship go through a training arc where maybe Emf has his title as champion threatened and Evbo struggles with being Not Human anymore.
This is where Seawatt comes in, right when they’re almost powerful enough Evbo slips away and contacts a dead Seawatt. Initially Seawatt wants nothing to do with Evbo or any of the living considering his mission is kinda over and his pride is still bruised but then Evbo tells him about the plan and how he deserves to know about it.
Maybe Seawatt lashes out at him for tampering with his home or puts doubt on Evbo that he could manage it. It’s initially a negative reaction but Evbo insists that it might give him closure.
He gets another opportunity, just a few moments to see how Evbo and Emf have tried to patch things up and return the layer to a more habitable place. It’s not to mock Seawatt or to upstage him but done to genuinely right a wrong, it’s made with progress in mind rather than stagnation.
This realization wouldn’t fix everything but it would mean a first step in reconciliation.
