Goddamnit woman! Why you do this to him?! You know he can't express his emotions well and has issues putting it into words! Including with his wife. Especially with his wife sometimes! Vegeta's own annoyance at her annoyance quickly overtook his tone, "Bulma." It all too easy to react to her anger and reflecting it back. Honestly, this was so often how they got into their shouting matches, one getting angry and the other then throwing it back at them.

Then a pause. And a huff. Them yelling at each other wasn't going to help anything. Well, it might... but that was part of the issue. So while he's not totally calm, Vegeta has lost a degree of that bite that had been in how he had said her name. "It's just..." Ughhh, "No goddamn privacy on this fucking train." Yes, they got a bit of time now, but... well... it wasn't enough, ok? Vegeta actually wants time with his wife. Alone time. Without a chance of others around. Like normal. Well, normal if a certain idiot didn't teleport in on them at random looking to train. Then again, Bulma was pretty good at scaring him back off.
