Y-yeah, that explains it. Not that it's a bad thing! He really liked you and you're pretty--ah.

[Just going to...smack himself with the letter to make himself shut up. Possessive of Grimm's grace, Alderic is not.]

Also you need to confess to someone. It's been five hundred years now.

[Which feels like an exaggerating. But maybe it's enough to put a timeline to when Grimm passes on.]
