The link between us shall be severed, for such is the will of God
This is true genius ! It explains much and is completely believable.
(We have a game here called "le téléphone arabe", where kids line up and the first one whispers something to the one next to him, who then whispers what he heard to the third, and so on until the last kid who says it aloud. Most of the time, the initial sentence has been distorted beyond recognition).

I love that Anna may be a Slayer, and somewhat a knight of Byzantium, but she's still a girl.

Ethan is totally believable too.

Great chapter!
