The Q
Hoop’s Villain, Reality’s Hero
Sure, it is a big deal. But there was no build up. From a story telling POV, it was throw-away. And she didn’t know about his powers going in, but I think she kinda put it together when he was able to create an already-cut diamond by compressing some coal.
The episode where she officially confirmed her suspicions was OK. The Uber-teen-angst manner in which she did it along with the faux-heel turn for Lionel was all a bit much, but the story telling device used was interesting. Was there a guest director for that episode?
Also they talked a lot about how Clark needed to tell Lana his secret to have a real future together.
him and Chloe talk about that multiple times in the first 10ish episodes of s5.
