The LuthorCorp bigwigs are getting ready to vote Tess (Cassidy Freeman) out on her ear when who should interrupt them but Oliver Queen (Justin Hartley)! Green Arrow has purchased controlling interest in the company and has plans for a serious house-cleaning… which are put on hold when a bomb goes off in the middle of his speech. Clark (Tom Welling) and Lana (Kristin Kreuk) take a break from their super-powered nookie to find out who's behind it.
A quick search of the blast site reveals fragments of kryptonite in the explosive, which Clark is affected by but Lana merely absorbs. Lex appears to be the obvious suspect--and he is--but since he's stuck in a coma he's had to outsource the project to a qualified representative. Enter Winslow Schott (Chris Gauthier), AKA The Toyman, who used to work for Oliver before he went crackers and started planting C-4 in teddy bears and things.
Oliver wants Lex out of the way for good, and he needs to keep Clark on the sidelines lest the Man of Steel harsh his mellow with some of that "killing is wrong" stuff. So he conscripts Chloe (Allison Mack) to pull Schott's file off the Queen Industries database. Clark catches her in the act, however, and the two trade ethical barbs until Chloe cracks and hands the file over to him.
Schott shows up at the hospital and tries to kill Oliver with a wind-up monkey bomb, but Oliver turns the tables before beating Lex's location (an ever-moving big rig truck) out of him and heading off to snuff the Bald One's candle once and for all. Clark and Lana arrive at Schott's lair to discover Lex's next target: the Daily Planet. They find the bomb on the roof, wired to a BIG chunk of kryptonite. Lana can defuse it, but in the process she'll absorb enough radiation to kill Clark, which was apparently Lex's evil scheme all along.
Lana submits and sucks up the green stuff, ruining Clark's long-term booty call for good. In a fit of hormone-induced rage he flies off to the big rig to break Lex's neck. Lana interposes herself between them in order to keep Clark from taking a life. As they stand there arguing, the truck explodes… thanks, apparently, to the same monkey bomb that was supposed to kill Green Arrow. Clark thinks Schott did it, but Chloe learns the true culprit: Oliver, who casually blackmails her into keeping quiet.
As Oliver assumes control of LuthorCorp, the kryptonite-laced Lana flies away rather than risk Clark's safety any further.
Oliver's back! Okay, he spends most of the episode in bed, but it's still great seeing Mr. Ends Justify The Means in action. Gauthier's super-creepy Toyman works wonders (Smallville always does well when it brings Superman's rogue's gallery into the mix), and the standard-issue combination of classic superhero tropes and soapy drama hits most of the right notes. "Requiem" also gets bonus points for that freaky last kiss between Clark and Lana.
Super-powered Lana. Pillow talk with super-powered Lana. Patrolling with super-powered Lana. Clark mooning over super-powered Lana in that smoochie-boochie way that puts rational people off their lunch. And all the while we wait for the painfully obvious other shoe to drop. The ponderous speeches grate on the nerves, Chloe still acts as nothing more than walking exposition, and the so-good-when-she's-bad Tess Mercer is nowhere to be seen. Boo.
Lana's out and Olivier's in… and that's more than enough to chalk this baby in the win column.
