It feels like a one-shot, character study. I'm thinking from Cordy's POV. Maybe a "softer side of Cordy" kind of thing, like what we see in those moments like when she's wearing the locket in "Bewitched, Bothered, and Bewildered." We don't see her being emotionally vulnerable often, but it's almost always about Xander when she is (on BtVS, that is).
