Why did Peter's face swell in space?
Why did Peter's face swell in space? Groot tries to extend his branches to save him as Peter's caught in space, but the coldness breaks them, and Star-Lord's face bloats and freezes as he seemingly dies. (Side note: Peter must have misplaced the cool headwear he had in the first film that allowed him to breathe in space.)
Will Chris Pratt return as Star-Lord?
Chris Pratt's days of playing Peter Quill will continue, as Guardians of the Galaxy 3's post-credits scene confirmed that the Legendary Star-Lord will return.

Guardians of the Galaxy 4 is unlikely to happen anytime soon, but never say never — particularly in the MCU. Guardians of the Galaxy Vol 3 felt like an end of an era, so a fourth instalment is not on the cards (yet) for Marvel Studios.
