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.
