This episode of Smallville was great. It was well thought out and made sense.
Seeing Clark overcome the obstacle without his Kryptonian abilities was very exciting. It gave him an opportunity to be the hero without having to hide his heroics.
Lex seemingly letting those freaks get loose to test Clark was kinda unexpected. Seeing Clark figure out that Lex was responsible, and then take the action to confront him about it was really awesome.
Then we get to see Clark and Lana get a little closer in the end sequence. This is interesting because it is something we’ve been longing for for quite some time.
