Welllll Alcuin has gotten things before that have either reminded him of the bad things that happened to him at home, or of Anafiel. Tesla doesn't actually know a whole lot about his past since he hasn't asked.

Or actually, you know what would be even simpler than an item would be Alcuin having one of his nightmares when he's with him. I just think it would be interesting to force Tesla to deal with him in a context other than smartAlcuin or sexyAlcuin. :)
