->''"I sacrificed Angel to save the world. I loved him so much. But I knew what was right. I don’t have that anymore. I don’t understand. I don’t know how to live in this world if these are the choices. If everything just gets stripped away. I don’t see the point. I just wish that...I just wish my mom was here.

->[[Creator/StevenMoffat Steven]] mentioned the fez to Piers and I before he even wrote it. He said, "I’m thinking of putting [[Creator/MattSmith Matt]] in a fez in episode 13." And of course both Piers' and my jaws hit the floor and went “A ''fez?'' You’re kidding me, you’re going to put Matt in a fez? [...] If we put Matt in a fez, Matt will never take the fez off! He will want to wear the fez for the whole of the next series! It will be ''glued to his head!'' [...] He’ll be wearing it, you know, with his own clothes! It will be a ''nightmare!"'' And he said, “No no, I’ve got a cunning plan; as soon as he’s got the fez, I’m going to kill the fez.”
