15. River's Death - Forest Of The Dead
The Tenth Doctor was just as confused as the rest of us when he first encountered the enigmatic River Song in the Library. As a mysterious figure from his own future, the Time Lord remained none the wiser about her true identity (Spoilers, sweetie!) but that didn't detract from the emotional grandeur of her noble sacrifice when she heroically gave her own life to secure their future together. Even then, she was the boss of him.
