I dont know about anyone else, but for me, this was the biggest tearjerker of Series 6. The Tardiss corporeal form is dying, and she doesnt want to say goodbye. She wants to say hello, while she still can. And the way Smith acts it, its just astonishingly touching. The Doctors really, totally heartbroken by the Tardiss departure, by her return to the box. Gaiman said in an interview once that he hadnt written the crying in this scene: Matt Smith did it on his own. The Doctor begs the Tardis not to leave. The Eleventh Doctor doesnt really beg helplessly very often: only when someone he cares about is going to leave him, and he knows theres nothing he can do. The Tardis, Amy, and Clara, he all begged not to go. And they all did anyway. Fun fact: when I started writing this article, I did not realize how bloody depressing it was going to get. Geez, Smith
