So…now I want to go see if there’s crossover fanfiction where Kaylee wanders on the TARDIS and starts fixing stuff and the Doctor is first cross because there’s a stranger fiddling about with his TARDIS and then he’s happy because she’s fixed something that was annoying him, so he invites her to be his next companion.
Things like this is why you just gotta love the internet. I had never even thought about it before and now it just makes a world of sense.
