If you have a plot, and Gamora happens to be trans, ok. If it’s about Gamora being trans, it’s not your story to tell.
It was gonna be Peter and Gamora just sort of sitting around discussing their lives/childhoods after the events of GOTG2. So they’d end up talking about all the lost siblings they had between them (cos Gamora has a ton of them too) and about how they both forgave a family member who wronged them (Yondu and Nebula) and just sort of general plotless stuff with Gamora’s gender (which she mentions once or twice I guess?) playing second fiddle to what she thinks about all the things the conversation is about, if that makes sense? One of those meandering affairs where nothing happens except a lot of Character
