"Because obvious you will! Clara, I've known you all my life, and I've dreamed of a different, but very similar version of you, and I know who you are. I know what you do. You try to help, try to fix what you can. You don't run because it's scary, you do what you absolutely must because you believe in the good of people..." Troy huffed, ignoring the fact he was describing the Doctor in his own right.
"You may not be reckless, but you're a good person, and sometimes you don't know when to stop," He watched her a long moment, then shook his head before finally sighing and standing to his feet and moving in a bit of a pacing pattern in the living room, then looked back to her, "It's not a gift. I told you from the very beginning I didn't want to be this man, I couldn't be this man... weren't you the one who told me to give him a chance? That he was a good person? So I gave him a chance, and guess what Clara? Hate him as much as I do, I am him and I get it."
Troy frowned, "He made a promise, and in a way I made that promise, because we are the same man. So, no, I'm not impossible to hurt but it's impossible to ignore things like black holes and potential murderers. I'm insisting that I need to know who he is, because someone has to do something, and considering his power? It can't be the police, can it?"
