pp shoots the gernade causing it to go boom. After everyone is regenerated pp sees Rebel Manta, who is constantly pissing him off, and rushes to permanently destroy her... Nah, that wouldn't be fair, I'll just hurt her very very badly.
pp takes Rebel Manta and sets her in the Ultimate Time Out Fortress where Rebel Manta is stripped of her normal clothing and dressed in crappy overalls. The walls are an infinite number of feet wide. Yes, they're cardboard, but it was cheaper than making a metal infinite width wall, right? Plus, it's still impossible to escape.
Any other form of escape such as telekinese has been blocked off. Let's see you get out of this one Rebel Manta, you and your superpowers and such. (Muahaha!)
