That's not really evil conversion (even though the Angelus can be a bitch sometimes). I can't remember which issue of Artifacts that's from (looks like #17 or 18), but it's a dream sequence where Dani, stripped of her memories in the new world, is slowly beginning to remember that she had been the Angelus host in the previous world. Ultimately it's Dani's girlfriend who becomes the Angelus host in the new world.
I have a hopefully informative page on
the Angelus on my wiki.
