Who am I? Well that should have been your first question. Names can carry a lot behind them, mine especially. The mere mention of my true name endangered the existence of an entire civilisation, but the name I've come to prefer, has been heard, praised, feared, and forgotten, over countless years in an entire universe... and you're about to hear that name. Remember this name, because I don't want you to ever forget who I am. Because, I've just realised, I haven't introduced myself yet! I'm the Doctor. Nice to meet you.

Trixie: [Distraught, on the verge of tears] But it did! I lied and lied and lied! None of them came true! I told stories of places I've never been to, boasted glories of bested creatures I barely knew even existed! And I got wrapped up in those lies and became something… ugly.
Doctor: And what did you do that for?
Trixie: [sobbing] Because it wasn't me. I was playing a part that I was not. I didn’t want to be me. Because I'm nothing special.
