Clark learns Kara is in Washington searching for the crystal. Kara is captured after she breaks into the lab and sedated with a kryptonite-infused truth serum. The serum causes her to relive a prior trip to Earth when she followed Clark's biological mother, Lara, to the Kent farm. Clark arrives in time to save her but, searing the machine with heat vision, he also falls victim to the serum and sees what Kara sees: his mother. Written by Anonymous

Did You Know?


Unlike Clark's Kryptonian ship (which was designed to hold him as an infant), Kara's ship was big enough to hold her entire family. It is basically the same size as Milton Fine/Braniac's ship from season 5, which also carried both Nam-Ek and Aethyr to earth in Season Four's Commencement. See more »


The year is supposed to be 1986, but the TV in the Kent's living room when Lara and Kara are there while they're at church, looks very 90's. See more »


Clark Kent: [opens Martha's portrait and find Lara's picture inside] I don't believe it. After all this time.
Kara: That means that I really was here, and everything that I saw was true.
Clark Kent: When I saw my mother in your memory, she was so beautiful... just as beautiful as she is in this picture. You really loved her, didn't you?
Kara: I did. Just like I love my father. Until now, I thought he was such a God--a real Kryptonian hero. But you're right. He was nothing like that.
Clark Kent: Your father did some terrible things. But in his...

Kara's storyline up until now has been revolving around her search for her missing crystal, with a few subtle teases being put in place regarding a questionable history between Jor-El and Zor-El. In this episode the storyline is taken to the next level. To be honest this is more of a transition episode than anything else. Nothing particularly interesting happens, but a few new twists are thrown into the story regarding Kara's father Zor-El, and Clark's biological mother Lara.

The real appeal in this episode is the brief flashback to the destruction of Krypton. This is one of the first real scenes we've been shown on Smallville of Krypton. For the first time ever we also see Lara, played by guest star Helen Slater, also known as the original Supergirl. How the flashback occurs ties in directly to an experiment in the 3rd season episode Memoria. It's always nice to have those loose connections to past episodes. While I like the unexpected direction they're taking the Zor-El and Lara characters, and I loved the one fantastic dramatic exchange between them, the downside of this episode is that it's basically nothing more than a set up for the episode of "Blue" still 2 episodes away. Not a bad episode at all, but not nearly as exciting on it's own. It's much better when viewed with "Blue" later on.
