Possibly because it's just to set up this shot of Cary holding a big polished hunk o' quartz. Oh man, it's this scene. Where they confuse science and magic again. You know, there are a lot of cool and interesting things to talk about in this episode, and this isn't one of them. Basically, Fred got a Geiger counter at a yard sale, and with this magic hunk of quartz inside of it, they can detect Quor-Tothian energy. Which they want to do so that they can track down whatever beasty may have come through the rift when Cordy and Groo were knocked out. It's all pretty nonsensical and requires Fred to spew more technobabble and the whole thing annoys me so that's all I'm saying about it. It's worth noting that Cary is finally wearing a suit again. Hooray! It's very red. I've decided that all of his clothes were probably burned up in Caritas, and that it's taken him a while to buy a new wardrobe. In fact, when he vanished for "Double or Nothing," he was probably out shopping. Shame he didn't buy something for Fred, because I think she's wearing one of Cordy's old shirts -- a pink sleeveless baby-doll number that seems to have been chosen for the way it emphasizes all of the wrong things about her figure. Cordy and Groo come in, and Cordy asks how Angel is. Gunn answers that Angel is "still being all mature" up in his room. Cordy goes up to talk to Angel, and Groo stares after her while a clarinet coos to make sure we get the picture.
