Lana steps past Clark and advises him not to peek. He stands still as Lana undresses behind him. Lana takes off her shirt, exposing a paddy pink bra. Clark gets happy. Michael Stipe could give a shit. Lana drops her bra on the pier. She removes her shorts and, presumably, her panties. Clark just grins. Lana runs and dives off the pier, and we see her sorta naked from a distance, although I'm sure that was a body stocking and that she's frigid from the Canadian water. Lana emerges from the water, probably trying not to die from hypothermia, and tells Clark it's his turn. Lana -- whose hair is pulled back perfectly in the water -- says she won't peek. She turns in the water. Clark undoes his pants, and we get a glimpse of blue boxers. He lets his jeans fall on the pier and dives in. No ass shot. Sorry, fans. Lana looks around for Clark, but he doesn't come out of the water for a long time, of course leading us to believe that maybe something happened, since there've been references to meteor rocks in the lake on the show before. The music fades and violins creepily enter the mix as Lana calls out for Clark. She's worried. The Ominous Music of Oh-Shit starts to play. Clark's head pops out of the water and he goes, "Boo!" Lana is mad, but only for a second. She splashes water at Clark and he splashes back. Water fight! Wait, isn't it fall, and school's already started and people were just wearing jackets in the last episode? When did it revert to summer? Lana and Clark tread water close together. Lana says, "I always said there should be nothing between us." "Now there's none," Clark says. It's not exactly Shakespeare, is it? Just as they're about to kiss, they hear a scream. A girl is running by the sandy shore and goes into the woods.
