The person responsible for reversing Thanos' actions in the comics has only been teased in the films so far, so unless they are going to introduce that person in the second half... it may fall to Captain Marvel to be that person instead.

But you could be correct, we haven't seen Hawkeye and Antman (they were name checked by Natalia as being under house arrest, but we know they are probably in hiding somewhere) so they may well appear in part two.

Also, how are Stark and Nebula getting off Titan? Maybe Nebula can jury rig one of the crashed ships, she is mostly technology herself, and Stark knows a thing or two heh... I'm guessing he may not re-use the new Ironman suit immediately.

You can probably see it... CM turns up...

"So, you're telling me that you've been gone since before the first invasion of Earth, and Fury didn't tell any of us about you? The sly dog!"

"What do you mean... FIRST invasion of Earth?!"

"Ah, kid, you've got a bit of catching up to do..."
