Being new to the area myself, I feel I should probably explain to you. Even if it makes me look like I'm standing up for The Doctor.
This place is weird. The people you meet might have...children they haven't actually had yet, or versions of themselves that are the opposite sex. It's like there are a million alternate realities, okay? And people have been plucked right out of their time and dropped into this one. So the Doctor we're talking to might be the doctor who existed for me but not for you. Like he was plucked right out of the months between me and you.
He wouldn't forget you on purpose. He might act like a git, but for the important things, he usually comes round. You probably know that already.
The only reason I know you came after me is that he remembers me but doesn't remember you. Either way, I'm glad he finds someone. In any universe.
