Really, Washington, really? Vegeta's not sure he believes that... but, hmm. Those around him had managed to stop him from hurting others, from going after the Trekers, as they had told him he had been heading that way. Ugh, he can't remember any of it... but it doesn't mean others have to know, so Vegeta has no plans to just advertise it out for others. But also not deny it if it's brought up. It's happened, he would have to deal with the fallout from it.

"I'm what happened last night. My people are capable of a certain transformation that I haven't had access to for decades. It's triggered by the full moon," To simplify it, it's really Blutz Waves but he doesn't want to go into explaining those, summing it up with 'a full moon' was easier to get the point across as it was the more common method of it happening. "And I had failed to take into account I may arrive at a planet during such a cycle." ...he had failed to prepare for that, and that's his fault.
