We get a shot of Wes and Fred, wearing gloves, bending over a microscope sitting on Cordy's desk. Kim: "...And they started playing this beyond industrial trash noise funk day and night. And then it happened to me. - You saw it. - Am I gonna turn into that?" Wes: "No. You're human. They're not. What's happening to you isn't permanent. It's just an infection." Fred: "Which you can get rid of by taking twenty milligrams of Cylenthium powder twice a day for a month." Lorne: "Mystical antibiotic. I'll get you some." Fred holds up a glass slide: "I thought your saliva was suspect. What with being green and all... No offense, Lorne. Under the microscope it showed traces of Penloxia." Lorne: "Oh - they're Wraith-ers." Kim: "Wraith-ers?" Wes: "Demons that can make themselves look human - for a time. (Shows her an entry in one of his books) Ten days, two weeks, then they revert to what they really are." Gunn: "I wonder why they would wanna look like musicians?" Angel: "For the chicks. Musicians get the chicks! (Everyone turns to look at him) What? They're gonna appear as dentists? Let's take 'em out. (To Kim) Where are they?" Kim: "In a rehearsal space. It's an old loading dock behind the shop'n'go in Echo park." Angel: "Wes?" Wes: "You'll have to kill them. It's the only thing you can do with Wraith-ers. You, Gunn, Fred can go. Lorne, stay here with the baby. I have some business to take care of."
