Since Charles strikes Anon as obsessive over Haytham...let's have him re-enact Edgar Allan Poe's Annabel Lee poem (http://www.poemhunter.com/poem/annabel-lee/). The poem is basically about this beautiful girl who dies and this guy who loves her to the point where he's claiming that even the angels are jealous of their love and thus have taken her away from him. In the last stanza, he lies by her side in her tomb, and there's a heavy suggestion of necrophilia.

Methinks it fits Charles perfectly, no?
