Gamora's sister Nebula is absolutely in 'Guardians of the Galaxy Vol. 3', and honestly, her arc might be one of the most emotionally satisfying parts of the film. If you've followed her journey from the first movie, where she was this tortured, angry antagonist, to now—seeing her as a fully fleshed-out Guardian—it's wild how far she's come. The dynamic between her and Gamora (or rather, the Gamora from another timeline) adds this bittersweet layer, since this Gamora doesn't share their history. Nebula's growth from a villain to someone who genuinely cares about her found family is so well done. Karen Gillan kills it with the subtle shifts in her performance, too.
And let's talk about that scene where she interacts with Rocket—no spoilers, but it hit me right in the feels. The way the script ties her past trauma into the present storyline feels earned, not just tacked on for drama. Also, her tech skills get some fun moments! If you loved Nebula before, this movie will make you adore her even more. I left the theater thinking about her character more than anyone else, which I didn't expect.
