Sometime later the turtles started train but most of the Leo stumbled or drops his swords when he felt pain. Splinter stopped the training to talk to Leo. He said that Leo is ban from training, Patrols or even leaving the Lair. Leo will continue when Splinter thinks it's best but from what Donnie has said Leo will not be ready for a few months. For Leo this is like being Mikey told that he's not aloud to have Pizza for a week. But instead of saying no or arguing he nods and hands over his swords to Splinter.
