[And to think, it took people three years to figure out these two were related.]

Running from what?! [Vegeta doesn't stop Trunks from getting up, still angry at him for defying him. For being stubborn. For having decided on such a stupid plan immediately. For making Vegeta so very scared for him.] I told you, we'll kill Black! You can even land the killing blow if that's what it will take to help you sleep at night!

But staying on your own in a destroyed future is just pointless obstinacy! And I won't allow it!

[Because unlike Trunks, Vegeta's plan that he's decided on immediately is a good one. Because it's his. So that's what they're doing, he spent a whole five minutes thinking it over.]
