Re: John Cena, Ryback, & Sheamus vs The Shield
Cena, Ryback, and Sheamus scheduled to face the Shield in a 6 man tag at EC. Early in the PPV (before this match), Ryback is attacked and taken out (with a steel pipe or whatever) by a masked man. Cena and Sheamus are given until their match to find a new partner. Orton comes forward and volunteers. He's been attacked by Shield too (I believe). During the match, Orton turns on his partners and helps Shield win the match. It is later revealed (maybe on RAW the next night) that it was Orton who attacked Ryback.
This would not only help continue to make the Shield look strong (as opposed to jobbing them out in their second real tv/ppv match), but it would turn the fans against Orton, which may be hard to do without aligning him with other hated heels.
