>>108898787The problem with that is as I said, unlike Star, Steven is not the kind to go for the kill. Even against WD he was unwilling to get violent, only attacking the ship so he could force her to see him in person. The movie trailer is the first time we get a hint he might actually fight for real and that's with a villain threatening to kill all life on earth, and even then it's probably trailer bait.
Short of attacking his friends there's nothing Star could do that would make him go at her to hurt or kill, and his attitude would likely just piss her off even more. People often forget to account for personality in battles like this but it matters a lot.
