If the sequence is correct, here it looks like Thor may be the one who escorts the FF into the Avengers Tower
What further suggests that Thor arrives with them is this next scene. The Thunderbolts are still in the exact same outfits (Bob's even got his socks and robe and all) as the post-credits scene where they see a ship entering the atmosphere
But if Thor arrives with the FF, how did he meet them? First Steps was set in an alternate universe than the main MCU. Does Thor somehow manage to cross the barrier between realities before anyone else?
And then to further back this theory, let's take a look at the Steve & Thor meeting. See, the way the trailer plays out so fast and all those clips scrambled out of order, I initially thought that this scene took place in the halls of the Tower.
But then I realized that the colors and the architecture don't match those of the Tower, but rather the FF's ship.
See how the halls have rounded entrances, just like the one Thor walks out of in the first screenshot of this post. Plus you can see some bots/gadgets in the background that resemble the FF's technology and not the Avengers' tech.
So maybe Steve has been travelling with the Four? 👀 There's already the theory that Steve is the one who Loki visits in this scene with the TVA card.
Maybe Loki is the one who leads Steve to the Four? Or viceversa? (So do we think that Steve's gonna tell Thor about Loki or keep it a secret? 🥹)
The team then goes on to find Thor, who is reunited with Steve aboard the Four's ship. The common denominator here being that Sue has her child, Steve has a child, and Thor has a child.
But Franklin has presumptively been taken by Doom. And as far as I remember, the Mjölnir was last in the possession of Love... so what's Thor doing wielding the hammer instead of her? 🥺
And more importantly, who is that standing behind Steve in this shot?! One of the Four... or someone else?? 👀
Honestly I really like how much protagonism Thor seems to have in this trailer. I hope the same goes for the rest of the film. It looks like he's gonna have a major part in bringing all the team together. And it was about time Thor got to be the leader!!
All I'm saying is that that seems like some pretty nice sun shining there on Thor 🥹☀️💚
