Robin learns that the boys' camp for would-be ninjas is being used to recruit thieves, and becomes trapped by Dragoncat and the villain's gang of killers.

Tim (under an alias) went berserk on the camp's "sensei" when he tried to show up a fat kid. He liked Tim's style and invited him into their gang. Robin took down the "ninjas" that night during Tim's initiation. He learned Ariana's family had sold their business.
