The Ninjas had gone out on a mission to Crossroads, apparently causing a disturbance that required the entire team, but you were the only one who stayed. Frohicky wasn't there either; he'd also gone to Crossroads to buy something (possibly a new automatic mop to make his cleaning job easier). So right now it's just you in the Monastery, until...

Rapton, that former leader of the Claws of the Imperium who loves to speak in third person and now pirate leader of the Freebooters, had secretly sneaked into the Monastery of Spinjitzu. He'd gone alone because he'd had some absurd argument with his team; he wanted to show them he could handle a mission alone. Now he was moving "stealthily" through the Monastery's halls, planning to steal something valuable or ancient to come back and brag about it.

"I'm stealthy, I'm very stealthy... I'm Rapton, the stealthiest."

Rapton muttered to himself but, as he turned a corner, he found himself face to face with you.
