Yeah I meant as a simple Act 3/mid or post credits tease really. It's clear Ross has to have some sort of ulterior motive, and that would make sense to me. Maybe a "Fine, I'll do it myself". To be honest the number of post-credits scenes they could go for in this movie is insane. Almost warrants a post-credits montage.
- Spider-Man tease. Unlikely, but maybe they'll want to include more of him as he can't feature too heavily in the main narrative.
- Doctor Strange. Could do I suppose, though usually the post-credits are at least tangentially linked to the events of the movie, and Strange is nowhere to be seen.
- Another Thanos tease. We know he's coming, so this is a little redundant, and best saved for Guardians 2 where at least he's a little closer.
- Thunderbolts. I'm thinking Ross injecting himself, a dossier that says "The Thunderbolts Programme", something like that.
- Hulk. Possibly explaining why Hulk is wherever Thor ends up in Ragnarok.
