It's wonderful just listening to him when he's so full of energy. He's talking about getting kidnapped, and it's all just a story to him. A story that shocks her and makes her smile all at the same time. She sits up while he talks, dangling her legs off the edge of the table, and he's just fantastic, everything about him is just fantastic.

Then it changes, no warning, his awe inspiring babble changes so fast into something far more reticent. He's rejecting her again, and it hurts. She can't even bring herself to question him, why doesn't she belong with him, it's so simple, so meant to be. Why can't he see that?

"I know Doctor, I know it wasn't your fault, you don't need to say sorry."

She's crushed, so she's responding to the part that doesn't matter, because it's easier than asking him why, it's easier than giving him chance to reject her again, it's easier to leave it hanging, not confront it.
