this is wonderful. simply wonderful. i love doctor who fic who can actually capture the sheer awesomeness of time travel. time's relative indeed.

okay, i love every single word of this but i have to say... LUKE!!! Omg, I've dying for good Luke characterization.

"It's complicated," said Luke. "I'm different; my molecules agreed more with the matter transfer than anyone else's, so Mum sent me as her delegate." He smiled. "She told me she'd explain it later, but I don't think she knows why it is."
