Daniel finds himself caught in her eyes, so large, the first time he sees her. It's her knowledge that draws him in next and even as he feels himself fall he tries to stall with thoughts that she’s only eighteen.
He resists until the argument, one he's not even sure how it got started. All he knows is that they're nose to nose and there’s a smile, not anger, in her eyes. He doesn’t think then, just kisses, lifts her onto his desk, cradles her head and finds himself thinking that whoever decided to hire Dawn Summers was a genius.
