Avengers: Endgame Super Bowl Trailer Breakdown - 13 Things You Need To See
10. Nebula Working With Tony
The first trailer had a lot of focus on Tony Stark's plight, with Iron Man seemingly alone on a ship and abandoning hope of making it out alive. The trailer also featured one shot of Nebula, which suggested they might actually be together, and this teaser confirms it.
Not only that, but it's not all doom-and-gloom for Tony at this point, as he's remembered that he's actually a genius and might be able to fix the ship himself, with some help from Nebula. Whether that works, or if they still need someone - Captain Marvel? Pepper Potts? Rocket? - to rescue them, remains to be seen. It also looks as though Nebula is using parts of herself to fix the ship, which shows just how dire their situation really is.
This could even be before the scenes in the first trailer, with them fixing the ship on Titan before attempting to head back to Earth, and things then going wrong on the way.
