Buffy the Vampire Slayer: Entropy

"You're lesbians, so the hating of men will come in handy!"

Anya's back, looking for revenge! And... actually we get a rather witty and thoughtful episode that mixes comedy with very good characterisation, hitting exactly the right tone in the way that only Buffy can.

Xander starts the episode in a terrible state, drinking bottles of awful, undrinkable American lager. Fortunately, Anya's return at least saves him from that awful (though perhaps deserved) fate, in spite of going terribly wrong.

Other stuff is happening, of course; Jonathan is doing some spell type thingy, while the rest of the gang (well, Warren) seem to have ominous plans for him. Spike is still threatening to tell everyone about him and Buffy. Buffy and Dawn are slowly reconnecting. But much of the episode, played for comedy and performed with superb comic timing by Emma Caulfield, consists of Anya trying to get each member of the cast in turn to curse Xander. Eventually she connects with spike, over a bottle of bourbon. Very well, in fact. To the point of doinky doinky. Unfortunately this happens right in front of one of many cameras installed by the three nerds, just as it's been hacked by the Scoobies- and everyone sees. Including Buffy and Xander, both heartbroken. And this time the anger between Anya and Xander is mutual. The whole fallout is simply brutal.

And then we get a final scene, perfectly scripted, where Willow and Tara, the sweetest couple ever, get back together. This is the perfect ending to an episode that really does demonstrate this programme's absolute mastery of tone. Magnificent telly.
