I don't know but we better see him get a hell of a lot stronger before the season is over and get an explanation for his current weakness.

Scott was just taking pain, which all the werewolves can do. What Derek did was different, only an alpha could do it. He was actually healing Cora, and it burnt out his alpha spark.
