Richard smiled at her as she entered. "Good, I was worried Jack might have cursed you." 

He was still in full-on spooky evening wear, though the makeup was gone, except for a few smudges. He looked(and felt) tired, but not nearly as much as her, so he felt it best not to complain. "We had to go see The Dante, had a bit of a potion emergency, you saw that part, at least." He conveniently left out the exact nature of the potion Jack had spiked him with. "We heard something interesting when we were there..."

He recounted the ghost story that Finch had told, including the details that he and Addie had remembered from their trip to the coffee shop. 

"We were just about to talk about it when you got here. I see a few things here. Professor Clowers is a vampire, and he's in some kind of rehabilitation center in Vancouver -- we'll have to look into that, there can't be too many of those -- and apparently he's getting better. They trust him with a wand now. I got to wondering if that had something to do with Hale and Lark. He's the last one to see them before they disappeared, he could have been a vampire that whole time. And as a Defense Against the Dark Arts teacher, I bet he knew about all kinds of dark magic, maybe he could even have erased a painting's memory."
