If anything after Avengers: Age of Ultron (2015) something that has always boggled my mind is how Bruce ends up on Sakaar? I mean we saw him flying the stealth plane in Hulk form and then he disappeared went off the grid and has been missing for years but then all of a sudden shows up in Thor Ragnarok shows up on all planets of Sakaar where he and Thor are reunited so it begs the question of how Bruce even ended up there in the first place
