"Six," Shepard responds as she finds one more for herself. Her voice is almost sing-songy as she says it. She really doesn't care about winning this so much watching him actually care about what they're doing. She enjoys the way his face looks when he starts formulating plans how how best to trick the rats out or the focus in his eyes and he gets more determined to beat her.

She isn't really trying to win but that doesn't mean she gives up completely. It's not as fun if he thinks he's already won.
