Are you referring to the quest in the desert? As it was supposed to be Only Rey's quest, and part of that scene was Kylo's purpose to show her true powers and he did. Or was it another scene you referring? < But yes I agree that everyone need not go and loosing Chewbacca in the process being caught.
Or the quest to reset C3PO?
As for Rose, no comment. She shouldn't been picked imo. I wont go in more because is bound to upset people on either side.
