I have no idea, I've always hated that pairing. Vegeta is a genocidal maniac, he has never shown the slightest remorse for his many, many massacres (at least not as far as I watched the show). I don't get why everybody just forgives him when he's obviously a murdering sociopath who doesn't care about anyone. It's actually revolting that Bulma
willingly has a child with him. In my opinion Vegeta is so far past the moral event horizon that there is nothing he could do to redeem himself, even if he actually showed any remorse.
Also, if you want a real Dragon Ball discussion you might want to go to
Kanzenshuu. They are the best DB forum I've seen and are still somewhat active. I don't have an account there, but sometimes I like to go over and read some of their threads.
