Maybe Eric had a point, though Dinah wouldn't admit that to him. Dean was one of the good guys-she'd seen enough evidence to believe that wholeheartedly. But Dean had also spent an entire life hunting the supernatural and in many cases, being hunted and tormented by the supernatural.
She didn't know if she could talk him into the truce with Eric. In fact, she had a sinking feeling that that conversation would turn into an argument. All the same, this was the best way she could think of to keep the City safe. To keep him safe. She didn't know if she could take Eric at his word, but she'd been watching him for long enough that it was believable that he wasn't going after innocents.
She gave him a strained smile.
"I'll worry about Dean. You just have... a Merry Christmas, I guess."
Now there was a weird thing to say to the vampire. Then again, the whole conversation held an element of surreality truly.
