That sounds as if it may be the episode in which Davis and Lara Parker were guest stars. I thought it was a two-parter, not a three parter, but I'm not very knowledgeable when it comes to the "Galactica" Universe.
You may get to see Lara modelling her Vampilique fangs in this one. I think she's on her way to a Halloween party and she's going as a vampire. Cute!
