Episode 2.20: Witness

Three thugs exhibiting super strength pull a heist on a Luthercorp van, stealing a large quantity of refined meteor rock. Clark intervenes but is unable to stop them. When he discovers that the meteor rocks are being melted down into a gas that can be inhaled, thereby giving the users their abilities, he must find a way to bring them down that does not involve getting too close to the meteor rock. Also in this episode, Clark and Chloe have a major falling out, when she accuses him of never being there for her. Lana decides to slow things down with Henry Small, after she learns that their relationship is putting a strain on his marriage, and Chloe is given a proposition by Lionel Luther.

Lana Lang truly is the third wheel of Smallville. It is only when you go back to these earlier seasons that you fully realise the makers of the show just do not know what to do with her. They have spent a considerable amount of time developing the story between her and Henry Small over season two and after his appearance in this episode he is never seen or heard of again. But his exit is unsatisfactory. Lana tells him to cool things off for a while so that he can mend the rift between him and his wife. We are completely led to believe that this is only going to be a temporary thing. So where the hell is he for the next eight seasons?! It just renders everything we have seen between him and Lana somewhat pointless.

The stuff that goes on between Clark and the three meteor steroid thugs is very entertaining. There's some cool action beats, including Clark almost being roasted alive inside a giant furnace, and some typically intriguing back-and-to between Lex and his father.

You really do have to feel for Chloe. When she points out Clark’s eagerness to drop everything, including her, when it comes to spending time with Lana, it is very easy to agree with her.
