Of Ice and Men - S2-E7

Question: Stan ditches Francine as a skating partner to skate with Roger because he's better than Francine and he does that because he wants to win the skating championship. Later in the episode, Stan realises it's not the winning that matters, then ditches Roger to skate with Francine not to win. But she declines. Why would she want to skate with him and not skate with him when he doesn't want to do it just to win?
