2x11 - Teen Titans

When Robin accidentally wrecks his R-Cycle while pursuing a nasty thug named Johnny Rancid, he winds up with his arm in a cast and doubt in himself. The good news is he gets a visit from his number one fan, a short little weirdo name Larry the Titan. The bad news is Larry's reality-bending powers than they can fix. Can Robin get his nerve back and take down Johnny Rancid before Larry's "help" breaks the fabric of time and space and destroy reality as we know it?
