Eternal was finally what I wanted from Smallville. An episode that had huge story development while still being an exciting episode that wasn't completely lacking light. Davis 'died' and then as I expected, and to be honest hoped, miraculously came back to life. Tess was being her lovely devious self and Clark was rather annoyingly denying everything. And then we had Chloe being forced to make a decision that could ultimately save or destroy Clark... and even the world.
Tess was my favourite aspect of this episode. I couldn't help thinking she was speaking sense, even if she was misguided a tad (or a lot) in her approach. Clark does need to face his biggest challenge before he can become superman. And I felt as though it was the writers almost telling us that 'no he isn't quite there yet' to all us eager viewers. Clark annoyed me in this episode. Tess knows for a fact who Clark is, and has told him that. And I just wish he would stop denying it as let's be honest it is futile. If he was to be honest with Tess then maybe she would be with him, and would take a better approach. I still don't believe she is completely bad, and her actions are justified in her own twisted way.
I must admit, for the split second I thought Davis was dead - I was annoyed. Had he died it would have been a complete anticlimax. So when he reappeared I was actually really glad. I did feel sorry for Chloe. Yes she was a bit dim in not recognising there was something seriously wrong with him. However her decision was a horrible one. First she had to decide whether to kill him, and possibly save Clark. Then she had to chose between Davis becoming his true self or staying with him so he represses the beast. I don't know about any one else, but hanging out with a serial killer and omnipotent destroyer of the world doesn't exactly sound like a thing I would want to do. At the same time though, I think she still has feelings for him and it took almost losing him to see that.
Overall, this episode lived up to the hype. It was exciting and developed the story really well. I cannot wait to see Clark and Doomsday finally fight as I know it will be extremely explosive and a great way to end a unexpectedly good season.
