The CW delivers some more new Smallville tonight at 8 p.m. ET. Last week was Labyrinth. Red kryptonite returns and affects Lois & Clark! Here is the official preview from CWTV.com. Smallville #6-13 "Crimson" After Lois (Erica Durance) tries on lipstick made with red kryptonite, she becomes overwhelmed with desire for Clark (Tom Welling) and makes her move. The two share a kiss, transferring the red kryptonite to Clark and his inhibitions immediately shut down causing "bad-Clark" to emerge. Fueled by the red rock, Clark decides to break up Lex (Michael Rosenbaum) and Lana's (Kristin Kreuk) wedding dinner and kidnap the bride-to-be. Allison Mack, John Glover and Annette O'Toole also star. Brian Peterson & Kelly Souders wrote the episode directed by Glen Winter.
