Vegeta was a lot of fun this chapter, I loved his "it's only postponing me dying again", and the dynamic with him and Goku is always fun. I like Goku waiting until Vegeta basically has it on before he tells him it's permanent, and Vegeta being upset about Goku holding back Super Saiyan 3 is fitting. Ultimately, it serves as a further reminder that Vegeta's family means more to him than his pride, that even despite expressing his anger at Goku, hearing Buu killed Buu and absorbed Trunks was enough to make him swear and put it on.
