Carpe Demon

I've been binging Charmed for the first time these past weeks and have been thoroughly underwhelmed to the point where I almost dropped the endeavour entirely. But this episode really stands out, and that is solely because Billy Zane is so great in it. The guy has to be the single best "cameo" (if you can call it that) in the entire show. He manages to not just portrait an demon who willingly chose to throw away his immortallity in favour of being able to experience a brief spell of humanity. He really pulls it off, convincingly.

Which is more than can be said even for many of the main cast on this show.
