Lets hope they do I guess. It could work that way yes. Klaus or Elijah or Kol goes, 'Switch on emotions' and he does. Then we just keep him down while he calms from the blood but he'll want to get off the blood. That's the difference.
Do people 'let' Klaus do anything? He's pretty much our worlds most infamous crazy ass psychopath. I'll do what I can for Rebekah but I hate what I'm going to have to have her feel. Its cruel Lee.
