In this episode we see the introduction of Oliver Queen, aka Green Arrow, and we discover that he and Lex Luthor have a contentious history, that spans back to when they were young. Lana Lang is trying to convince herself that she made the right choice in picking Lex, by demonstrating loyalty to Lex even though he is doing things that she doesn't agree with. We see a first as Clark Kent gets sick for the first time in his life with a head cold no less. Everytime he sneezes there are disastrous consequences. We see him discover, with Chloe Sullivan's help, this new superpower and we see some humourous attempts to control it. I liked this episode as it was good to get back to a story where Clark is still discovering powers. It is reminiscient to how this was happening in the first couple of seasons of Smallville, when Clark discovered his x-ray vision, his laser beam shooting eyes and his super hearing. FULL REVIEW:
