Okay. His answer, at least, made sense. He was from right before Megatron had, in fact, ripped in him half. Her stomach churned as she tried to decide whether to tell him that fact or not, and finally decided against it. That was something best left unsaid. Or, if anything, said by Bumblebee.
So she decided not to comment on the battle itself, except to smile and state simply, "Well, I'm from a while after that battle, actually. We won, of course. In fact, Sam killed Megatron." Her chest ached at the mention of her ex, but she supressed the pain that thinking about him caused and focused on how happy she was that Jazz was here and very much alive.
"And yeah, Bee is here. He's... different, though. He's, uh..." She lightly scratched at the top of her head, glancing away for a second before sighing and looking back at the Autobot. "He's human, Jazz. He suddenly turned human right after he showed up here."
