Episode 2.2: Heat

Heat is possibly one of the funniest episodes of Smallville ever. Learning that Clark's heat vision comes from his feelings of sexual arousal is just a classic moment. The part where his father helps him to control his new power of heat vision by getting him to think about sex is also quite hysterical.

With a teacher like Desiree Atkins there's no wonder Clark is getting a little hot under the collar. She has the power to make men do whatever she wants after the meteor shower heightened her pheromone levels. She soon has Lex eating out of the palm of her hand, and before long they are married, her plan being to have him killed so that she will inherit his fortune.

Lana's suspicions towards Clark are now seriously growing as she finds it hard to shake off what she 'may have' seen during the Tornado. Though, let's face it, it's about time she started asking him questions.

This is a top standalone episode filled with lots of humour and great character moments too. 10/10
