After finishing the Dawnguard storyline, I kept Serana for a while as a follower, but eventually I get fed up with her resurrecting every single dead body in the vacinity and leaving ash piles everywhere and booted her out. Now when I try to get her to follow me again I only get the options to become a vampire lord or make blood arrows. What do?

Try this.....travel to Castle Volkihar and enter using the side Undercroft entrance. Wait a few seconds and Serana should appear behind you (and following already). You can then leave and she'll follow until you dismiss her (just go back to Undercroft if you want her again). It's worked everytime for me (PS3), but I don't recommend using the "wait here" command, the "follow me" option doesn't appear and she just stands there. Hope that helps !!
Illia of Darklight Tower does the same thing. kind of reminds me of my ex-wife. and you can't get your stuff back without killing her....also...like...my...ex.....i may have said too much
i even had her take Kharjo's Moon Amulet so i could keep track of her...also like my....no, no, i kid. but it didn't help: i could find her, but she wasn't signing on for another hitch no matter what i tried.
then i couldn't get my next follower to take the Amulet from her cold, dead body so i could track her....go figure
