Was he surprised that she didn't lose her cool after hearing what he had to share? No, not really. She had been kind of calm about it before when he told her. "I'm sorry. I wish we could have found everyone a lot sooner." Maybe then she would still be alive back at home. Too many people ended up dying. But that was just life in the supernatural world.
He reached out and grabbed her hands. "Hopefully you'll get to stay here longer this time." He knew they all would all get sent home at some point. Their lives never changed while any of them were here. There was still that theory of clones taking their place. He didn't think that way. especially since he had been sent home, lived out a few years of his life, and then was brought back to the hotel again. "I'm also sorry I had to tell you this stuff. But I thought it would be better if I told you now instead of someone saying something at the wrong time."
