As a general rule, Eccarius is only after human blood (although he can subside on animal blood) or the more powerful blood of other vampires (even if his boyfriend had been a bit of a spoilsport about him making them just to kill and eat them). So, whatever Finn is, it's not currently on his menu.

"Of course on the other hand," he adds conversationally, 'perhaps it's just the statue that's attractive, what with the shiny metal and jewelled eyes. In the flesh he might be a bit more... moth-like." Which is to say motley greyish, excessive body hair, etc.

"Lizard person, really? How intriguing."
