Oh right, maybe he should have announced himself and introduced himself more officially but he was just so happy to see her that he couldn't help but sweep her up into a tight hug. Oh she was real and alive and he couldn't believe it. He had been so sure that she had died and wasn't going to regenerate then, it had been awful. Clearly he just hadn't stayed long enough. That would be one of those things he would regret. Still though, he was just happy to have her back.
"Right, I've changed again. Did I explain all that? The regeneration stuff? I mean it's part of why you woke up, though you didn't change. Which is amazing by the way." Very handy, to keep the same face, he mused. She got that babbling from him undoubtedly, but still he hugged her tighter again. "The other two don't know.. oh they must have been before. I'm sorry. Did you tell them?"
He wasn't sure how he was going to deal with his former selves around. "I'm so very glad you're here too." As far as things that made his death a little easier, this was definitely one of them.
