How possessive should Sebastian be? I can see that our demon butler would be possessive of Ciel and wouldn't want others near him (daw, how cute). But he's not the type to be romantically jealous - he just sees Ciel as his meal that no one should touch. It would be interesting to play out Sebastian's reactions, and yet I don't want him to become an obstacle. Any thoughts on how we should have Sebastian react?

Maybe Sebby could try and find out more about Alex and thus eventually uncover the secrets of your OC?
