"Hmm? I thought you were a Doctor of everything, and you don't know about the Dragon Balls?" Bulma replies teasingly, but any playfulness drops as she notes the hurt in his expression.

Trunks noticed it too, and paused again. Not eating, just thinking for a moment, before he spoke. "You still feel the loss." Somehow, he was sure he was right about this--even if he didn't know the details. "You tried to push me out of the way, when the ki-blast hit. You weren't surprised at details of the war, slipping into your story so easily." Okay, maybe a hint of suspicion too.

Carefully, gently, Bulma reached out to rest a hand on the Doctor's forearm. "We all got off on the wrong foot. But we understand pain that sticks with you." Soft, offering to listen, as well as to speak. "We can tell you what happened here, if you let us know where the gaps of what you know about our world are."
