Clark once again becomes "under the influence" of red kryptonite, and will say his true feelings on such things as Lionel and Martha's relationship, and Lana's pregnancy, but there may be someone else that will get affected by the red k.

On Valentine's Day, after Lois tries on lipstick made with red kryptonite, she becomes overwhelmed with desire for Clark 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 and Lana's wedding dinner and kidnap the bride-to-be.

Clark's true feelings
10 October 2007 | by Rcwilkinson123See all my reviews

This episode has appeal in two vastly different directions: one is sexual and annoying, and the other is plain cool.

These differences involve Lois getting infatuated with Clark due to putting on some weird red lipstick that makes her fall in love with the first person she sees. This person is Clark. This part of the show seemed a bit strange, but the next part is awesome.

Since Lois is on the strange lipstick, she gets Clark to get red kryptonite to alternate his character. As a result, he shares his true feelings about his mother's recent relationship and closeness to the Luthors, the fact that Chloe is at the wedding banquet, and most importantly, his feelings about Lex, Lana, and their upcoming marriage. This leads to a fantastic conclusion where he kidnaps Lana and has a very interesting showdown with Lex.

One of the best aspects of the entire series is when Clark shares his true, unabridged opinions on things centralizing in his life. This can only be done through the presence of red kryptonite. I wasn't a fan of the Lois-infatuation angle of this episode, but the climax that it produced was great.
