On Valentine's Day, after Lois tries on lipstick made with red kryptonite, she becomes overwhelmed with desire for Clark and makes her move.

According to an interview with Annette O'Toole, she disagreed with the writers and felt that given Clark's tenuous situation with Lana and Lex, Martha would never have agreed to attend their engagement dinner. See more »


As she gives Clark the mixed CD, Lois says, "Most people don't think Whitesnake sing power ballads, but they do." However, there isn't a single Whitesnake song listed on the CD. See more »


Chloe Sullivan: I did some digging into our favorite Martian Manhunter, but it's just coming up empty.
Clark Kent: Yeah, but we have another man-hunter to worry about. Lois.
Chloe Sullivan: Why does that make me picture her wielding an ax at every man in Metropolis?
Clark Kent: She's only after one man. Lois is... into me.

Chloe Sullivan: Wow. She really pulled out all the stops.

Opening the Heart, Damaging Relationships
8 May 2008 | by (Rio de Janeiro, Brazil) – See all my reviews

On the Valentine's Day, Clark and Lois are alone with broken hearts and meet each other in a party in The Talon. A woman in a stand offers a red-colored lipstick made of red kryptonite to Lois telling her that she would fall in love for the first guy she put her eyes on. When Lois sees Clark, she has a crush on him and full of desire, she kisses him. Clark is affected by the red kryptonite transferred through her lips and crashes Lex and Lana's engagement dinner party with Lois; he tells his true feelings to Lois, Martha, Chloe and Lana, and kidnaps Lana, opening his heart and damaging relationships.

The episode "Crimson" seems to be a plot point in the whole "Smallville" series. The "bad Clark" affected by the red kryptonite spoils his relationship with his mother and girl friends, inclusive the romance of Chloe and Jimmy. How his reckless speech will affect Martha, Chloe, Lana and Lois in future? The mystery about Lana's baby is intriguing with the last line of Lex to her doctor, but this episode has a huge flaw. How could a wrench or spanner be bent by a regular man without superpower hitting Clark? My vote is six.

Title (Brazil): "Carmim" ("Crimson")
