  1. The incredible hulk isn’t MCU…

    No, the avengers dont know about Coulson.

    I’m pretty sure Hela isn’t actually Death, just the ruler of Hel.

    I mean, Rogers was never really a captain in the first place, just a private, right. (Oh, how I love pointing that out.) I’m really hoping Wilson becomes Cap, that would be awesome.

  2. Here’s one.
    The Marvel Netflix series takes place in the same universe as the MCU. (Daredevil, Jessica Jones, Luke Cage, Iron Fist) How come we do not see Avengers Tower when it shows shots of New York?

  3. #10 Many of the leaked files were redacted. Also most of the stuff was still locked behind lines of code. This was discussed in avengers age of ultron as well as AoS

  4. #2 Thanos was probably willing to sacrifice the mind stone to get the space stone (or maybe get both). In the Avengers 3 trailer he has the space stone FIRST then the power stone. This is because with the space stone and gauntlet, and knowing where all the other stones are, he can go get them. Which is what is going to happen in Avengers 3.
