Okay am I the only one who noticed they where playing old themes from different doctors throughout this episode? For example, in this "oh brilliant" scene, the bad wolf theme was playing, and earlier in the episode when they were showing the 1st Doctor his future lives the 11th doctor's theme was playing. I got so emotional at that point when I heard it because 11 is my favorite therefore that theme is my favorite and I got so sad/giddy when I heard it because I was remembering all the good time
