The angle where The Shield brought out a beaten Christian was done to get heat on Triple H and his current regime.
Speaking of Christian, he is currently out of action due to suffering a concussion. That is the reason they never showed the "attack" from The Shield and simply dragged him out on stage after they had already "taken him out". He will not be back in the ring until cleared by the WWE medical team. We're told he passed his imPACT tests but hasn't passed WWE's secodary testing yet. He was also complaining of headaches and dizziness.
