One Day Earlier

Chloe isn't thrilled with the prom and Lana isn't planning on going due to her reputation with Jason. Chloe persuades her to go but Dawn Stiles, the school snob-chick, barges in and announces that Chloe has been nominated for prom queen due to her article. Out in the woods, Lex is taken to see a corpse – that of Dr. Bridgette Crosby. Jason wanders over there as well but Lex blows off his concerns. Back at the school Clark convinces Chloe the vote for her is a protest and then admits he doesn't have a prom date. Chloe tells him he needs to get out of his rut as well. Dawn discovers her boyfriend Billy is hitting on a freshman and reads him the riot act, and he refuses to go, breaking up with her. She needs a new date and as she drives home she spots Clark in the yearbook and sets her sights on him. Focused on the phone, she drives off the road and her SUV crashes down into a ravine and right next to some green kryptonite. That night, she wanders onto the road as Martha drives by, only for her to run right over her. But she's intangible and is "absorbed" into Martha's body, taking control of it.

Clark returns home to find "Martha" dancing to loud music and eating ice cream. "Martha" becomes very insistent that Clark go to the prom and insists he'll go with her. Lois arrives and "Martha" accuses Clark of planning to go with her then storms out. At the Talon, "Martha" hears her friends dissing her behind her back then confronts Lana. Touching her, she jumps into Lana's body, leaving Martha who ha no memory of what happened. "Lana" confronts Clark and asks him to the prom. "Lana" helps with the prom set-up committee then goes after Billy. Grabbing an electrical cable, she electrocutes him in the locker room while Clark meets with Chloe to find Lana. Clark notices the power loss and rescues Billy and spots "Lana." She jumps into a new guy, leaving Lana to try and explain what happened, then jumps several more times to cover her trail, ending up in the body of Dawn's friend Harmony.

While Clark is at the hospital with Billy, Chloe and Lana compare notes and start to put things together. Dawn is in a coma at the hospital. They meet Clark at the hospital and "Harmony" shows up to pay a visit as well. "Harmony" isn't happy with her disfigured physical body then jumps into the nurse and shuts down her corpus. Meanwhile, Jason is checking Lex's e-mail when Lex comes in. Jason confronts Lex, noting he has an e-mail from Bridgette Crosby and that they were going to discuss an artifact. Jason isn't satisfied and goes to talk to Sheriff Adams. Lois is at the Smallville Clinic about her allergies when the "nurse" confronts her. Martha and Jonathan prepare to go to the prom as chaperones and Clark is still staying behind – until "Lois" shoes up in a prom dress and demands he take her to the prom.

Jason takes Sheriff Adams out into the woods to show her the body but now there's a gazebo that's been there for years. Sheriff Adams is less then impressed, particularly since there's no record she ever existed. After she leaves, Jason calls his mother and reveals he and she had something to do with Crosby's death – he has one of the artifact pieces and they planted it there so Lex would get rid of it for them. Clark and "Lois" show up at the prom and then Chloe arrives. Chloe is announced as the prom queen, much to "Lois"'s disappointment. Dawn leaps into Chloe, leaving a puzzled Lois, and then "Chloe" makes an out-of-character acceptance speech thanking Dawn. When the crowd cheers Chloe, "Chloe" gets irked and storms off.

We catch up to the opening sequence – "Chloe" grabs axe, coldcocks Jonathan, spills oil, prepares for ignition. This time around, Clark spots Jonathan who explains Chloe hit her. Clark asks his dad to "get something for me." Clark arrives and catches the flaming mop before it hits the oil. "Chloe" grabs Clark and Dawn jumps into his body. He stuns Chloe but Jonathan arrives with some green kryptonite as Chloe secretly looks on, faking unconsciousness. Dawn is forced to leave and dissipates up through the roof. Lois gets her explanation and is (relatively) okay with it. She turns down his offer to dance but Lana shows up and the two get together for a dance. Lois advises Chloe to focus on the future and that Clark doesn't have much of a future, much to Chloe's amusement. Even Martha and Jonathan get a dance, while Jason looks on as Lana and Clark dance.

The WB has yet to release an official description.

Chloe (to Lana): You can help me bring stag back in style.

Dawn (to Chloe): I would say may the best one win, but we know who that's gonna be.

Chloe (to Clark): I think the future holds a lot more for you than you realize.

Dawn (to herself while looking at Clark's yearbook picture): I need some of this.

Dawn-as-Martha (to herself): Holy crap! I'm Clark Kent's mom.

Lois (to Dawn-as-Martha): There will be a man on the moon before Clark and I go to the prom together.

Chloe (to Lana): What would the senior prom be without a body-snatching prom queen.

Lex (to Jason): Burying bodies in the backyard isn't exactly a hobby of mine.

Dawn-as-Lois (to Clark): Anythings possible Clark. Anything

(to Clark): Did you pin this on me?... It's a little close to the boob, don't you think?

Dawn-as-Clark (to Chloe): The crown's mine bitch... genius.

Chloe: You know Lois, I think Clark might have more to offer than you realize.
Lois: I wouldn't bet on it.

Clark: May I have this dance?
Lana: I thought you'd never ask.

Lois the Enhanced is asked to dance by Clark after ending up at the prom. But instead of saying, "Hey, give Chloe a pity dance," she directs Clark to dance with Lana, who just walked in looking preternatural for the occasion. She and Clark dance while the band Lifehouse serenade Lana on behalf of Al and Miles. Jason, who was there when the body of poor Margot Kidder was found on Lex's estate earlier in the episode, sees this dance and gets angry. Which fits with the plot twist that he's now evil and conspiring with his mom against Lex. Good for him! Chloe is told by Lois that she'll soon be free of all this horrible treatment she's suffered. I'm not so optimistic about her chances. (TWoP)
