Tim and Damian are acting in character though. As Damian himself pointed out, Tim's the one who has given him the cold shoulder and looked down on him since they first met. I'm not condoning Damian's behavior by any means, but he does make several good points about Tim, and seems to LOVE to antagonize Tim. Tim really does make it easy for him to do so. The point was that they were being petty with each other as you say. That rematch was a long time coming too...even though there as no real result from it lol.
