Tenth Doctor Month: Quote Of The Day #4

The Doctor: Hello Sarah Jane.
Sarah Jane: It's you Doctor. Oh my god, it's you isn’t it? You've regenerated.
The Doctor: Half a dozen times since we last met.
Sarah Jane: You look... incredible.
The Doctor: So do you.
Sarah Jane: I got old. What are you doing here?
The Doctor: Well, UFO sightings, school gets record results. I couldn't resist. What about you?
Sarah Jane: Same. *They both laugh.* I thought you'd died. I waited for you and you didn't come back, and I thought you must have died.
The Doctor: I lived. Everyone else died.
Sarah Jane: What do you mean?
The Doctor: Everyone died, Sarah.
Sarah Jane: I can't believe it's you. *Mickey screams.* Okay, now I can.
