How is Loki escaping with the tesseract supposed to be part of Avengers Endgame? That timeline is deemed as an alternate one, so how would it be part of the film? I do have one theory though, after the Loki Season 2 finale, infinite timelines were created, so maybe we could have been watching that bit of the film in an alternate timeline, because no one talks about what happened with Loki escaping with the tesseract after they get back from the time heist. It’s probably just a scene marvel added to drag on the film longer and to start a show about the TVA.
Also, another question, how is the sacred timeline, sacred, when they still have the old gamora in it? Did they erase the timeline thanos came from in Avengers endgame? This whole thing is so confusing
