We know how “Avengers: Infinity War” ended and we know form “Avengers: Endgame” trailers that few Marvel heroes are in danger.
In recent trailers released as promoting materials, we’ve seen Tony Stark and Nebula have been stranded in space. They are trying to save their lives. As we noticed Tony Stark using his specials skills and what has left from his Iron Man suit is trying to send an SOS message for Pepper Potts. We can assume that someone on Earth could receive this message and prepare a rescue mission.
On Reddit we can read an interesting fan theory about this issue as Shuri, the Black Panther sister will be involved or thanks to her Nebula and Tony will be saved.
What do you think about that?
