A houseguest after a fashion - Buffy's husband's visiting son is a houseguest in this one:
Oedipus Calling by Addie Logan
Summary: Buffy Summers is sure she's found Prince Charming in her new husband, Liam Angelus. However, when a surprise house guest changes everything, Buffy learns how quickly a dream can become a nightmare.
There really are more where Buffy is the houseguest actually, at least in all human stories. Now, in more alt/canon stories it tends to be the other way around mostly, due to the whole 'Spike in the basement' precedent from canon. I'm not sure I really think of that as a 'houseguest' though. Problem is he's either canon 'Spike in the basement' or a live in lover in most stories and I'm not sure if either fits your criteria of 'houseguest'. |
