A normal person would be running, cowering, something in the face of a ki blast carving a path toward them. Bulma, though... Bulma doesn't flinch. As much as others may think that she maybe shouldn't, Bulma does have implicit trust in Vegeta. After all of these years, and after many moments of conversation or even just silent commiseration.. she knows she can break through to him.

Which appears to be a safe bet as the blast goes away, and instead Vegeta chooses to... bark at her? Bulma pauses for all of a moment, brain catching up after she'd been preparing to maybe take a ki blast without any bit of defense. But ever the one to not miss a step, she's quickly back to firing off.

"Come down here and say that to me in a language I understand!" Of course she has to say it - would it be Bulma if she did not? She points to the ground with a vicious level of seriousness, and fires off again.

"Get back down here where I have to look down to look you in the eye!"
