"Oh, Donna. I'm sorry. I'm so sorry. I didn't mean ... It's lovely to see. Brilliant. It is. I never thought ... Well, it doesn't matter. You're here. That's what's important. Don't worry about River. She's fine. River's fine." A fresh wave of pain washed over him, and he reached out to steady himself with a hand on Donna's shoulder. He forced himself to breath slow and steady until he could compose himself again.
"I need to get back to the TARDIS. There's something ... Something that's going to happen. Soon. I'm holding it off as best I can, but I don't know exactly how long that will be. You said Rose knows me when I wore a leather jacket. What about Martha? Is there anyone else here? Anyone I should know? What about strangers? Anyone who shouldn't be here. Anyone at all." If Donna was here, and Rose, how many others were present outside of their proper timelines? The Doctor's mind was working furiously. Rose was here. He couldn't change. Not now. He had to find a way around it, the way he had before.
