Leo has to think about that one for a minute. He is upset. But then, he's long recognized the patterns in his own behavior whenever this happens. This isn't new. When it had been Raphael who disappeared, all those months ago, Leo had pulled away hard. Severed contact with his cousins with the full intent to keep it that way.

If the Little Ninja hadn't sought him out, resonating with that quiet hum that Leonardo still hears on quiet nights, he'd have disappeared completely into the city. Even he doesn't know where he would have been when Raphael returned, instead of right at his side where he belonged.

Finally Leo relents, leaning his elbows onto his knees. "I saw who Monet was... the person she was afraid of becoming. It reminded me of a lot of the people we've seen over the years." He shakes his head. "I guess there was some Karai in her. There always had been. But she was different. She didn't let it control her."
