I kind of want to know as well is there anything from the comic books to confirm they were romantically involved. I know people ship them and that’s just fandom doing fandom things. But I watch stuff from the Telltale game and found a part where Peter does ask Rocket if he loved her. And well I do wonder if that has any form of proof to their relationship being romantic. It also makes me wonder cause in the movie I kind of thought of her as an adult when Rocket was basically a baby so I question their age range. But Rocket does seem more attached to her. I just want to know if there’s anything in the MCU canon that confirms their relationship being romantic or just being friends.
There does seem to be a lot of sources saying they were.
