The Time of Angels:
"Well then, the angels have made their second mistake because I'm not going to let that pass," the Doctor said into the radio, "I'm sorry you're dead, Bob, but I swear to whatever is left of you, they will be sorrier."
"But you're trapped, sir, and about to die."
"Yeah, I'm trapped. Speaking of traps, this trap has got a great big mistake in it. A great big, whopping mistake!"
"What mistake, sir?"
The Doctor looked at Amy, "Trust me?"
"Yeah," she nodded.
He turned to River, ""Trust me?"
"Always," she replied.
Then to Angel, "Angel?"
"Would I still be here if I didn't?" she countered with a small sad smile.
A/N: Why is Angel's smile sad? Not saying anything.
You guys killed me with this vote! The Time of Angels won by 2 votes, with The Lodger second, and third as The Eleventh Hour. I have to say, I'm actually relieved this one won, The Lodger was packed with mentions to a sub-plot I'll have running and, putting in the wrong drabble, would completely give it away and I didn't want that so thanks :)
