Well you'd better start getting used to it because I'm not going anywhere. There's world saving to be done after all!
It's what the alien race was called. Kind of like intergalactic bounty hunter/peace keeper types. They knew their fugitive was hiding in the hospital where I worked so they did the easiest thing, for them. Transported the entire structure and everyone in it to the moon so they could search it. That's when I met the Doctor.
