She was traveling to Gallifray, landing in England, being thrown down a mine shaft, and dealing with the fact that she was taken from her blue box body and put into a human one. This was to name a few of the things that were happening for her in one second/the life time of the universe. All different times, with different Doctors and different strays. This was what it was like to live in a non-linear fashion.

His chin really was hilarious.
