Pool. Pheromona is swimming in a red bikini, sans top. Bo walks in (the Luthor home has no security at all?) just as she's getting out. She greets him as "Mr. Kent," making no attempt to cover herself. Bo is perplexed. He's used to seeing udders on his cows, but nothing like this. She asks if he's there to talk about Clark. He says he is, and that he'd rather do it fully clothed. He tosses her a bath robe. She puts it on and apologizes. She goes over to Bo. She says that Clark is disturbed. He starts fires and takes credit for putting them out. Bo says that Clark was nowhere near her car. "Your son is lying to you. I'm sorry," she says. Eeeevil! Bo gets frustrated and starts to leave. Pheromona stops him. She says it's because of Lex. Bo turns around and she moves toward him with a full-on blast of pink fresh breath. Funky, sexy music is playing. With Bo enthralled, she says that she needs him to do something for her. Bo nods weakly. They kiss.

Smallville jail. Lana and Chloe are visiting Clark. Chloe apologizes for not baking a file into a cake. Lana has good news. They did more digging on Pheromona; she has a sordid past full of black widow-like dalliances. They found out she was around during the meteor attack. Chloe supposed that the girl and her then-boyfriend were getting it on near the lake at the time. Five years later, Desiree was a teacher who married a rich guy and had a student off him. After a second marriage, she lost all her money on dot-coms, and then went after Lex. It almost seems too convenient. Oh, but this is Smallville. Chloe has already figured out the pheromones, too, with absolutely no proof. "Lucky for us, Clark seems to be immune to some members of the opposite sex," Chloe says. Oh man. Yay, Chloe. Way to lay down the smackiness. Even Lana is amazed. Chloe ups the ante with an eyebrow-raise. Welcome back, Real Chloe. The girls are told to leave by Ethan. Clark mentions that his dad went to go see Desiree. He wants out of jail. After they leave, Clark notices the fire alarm. We cut to Ethan's desk as the alarm goes off. Ethan opens Clark's cell in a panic and tells him to follow. When Ethan turns around, Clark is gone, and there's fire.
