Note: Um, so. This fill A) has approximately nothing to do with the prompt (though Susan does technically sleeptalk, and is at home during a thunderstorm), B) isn't especially fluffy, and C) accidentally turned into a fic that I kind of implicitly promised
[ETA: The slightly revised final version is now up on AO3!]
( But Every Hour Is Saved from That Eternal Silence )
Do not go looking for Alice in BtVS or AtS canon, either television or comics. She's an OC invented specifically for this fic.
