Poor Nine. He WAS so impressive. If you skipped Nine, either go back and watch him now, or we can't be friends. maybe we can be friends, but only because I'll try to persuade you to go back and watch Nine.--> Nine is too fantastic to be skipped.
*Spoiler* If you haven't gotten that far in Doctor Who. But when I found out that he was The Face of Boe, I kind of figured it out before, but it was still a big surprise. The people of BBC really do know what they are doing.
