Ep 4. Devoted

Clark is facing a major challenge in the fourth episode of the fourth season of Smallville. The episode titled 'Devoted,' deals with the issue of subliminal messaging that is seen as highly controversial in the town of Smallville. The story begins when a young woman named Molly Griggs happens to gain an obsessive attachment towards Clark. As the plot unfolds, it is revealed that Molly has been unwittingly brainwashed to do so as part of a business experiment called 'Extreme Enhancements.'

The episode also deals with the usual struggles of life in a small town, as Lois Lane, a prominent character in the series, takes a job at The Talon. Having come from a big city, Lois finds it hard to adjust to life in a small town, but she is determined to make do with what she has.

One of the highlights of the episode is the chemistry between Clark and Lana. The two have been friends since childhood, and they are shown trying to mend their relationship after a string of misunderstandings. However, things do not go as planned when Lana is seen with a new boyfriend, Jason Teague, played by actor Jensen Ackles.

The episode also focuses on the power of image, as well as the way people perceive their surroundings. While Molly's character is seen as over the top, it brings to light the idea that subliminal messaging can indeed have devastating consequences. It also raises questions about the extent to which businesses can go to attract customers.

As usual, the show's special effects are quite impressive. The scene where Molly is lifted off the ground in a trance-like state is particularly compelling. The use of lighting and sound in this episode is also on point, adding to the eerie feel of the narrative.

Overall, Smallville season 4 episode 4 is a well-executed episode that touches on many relevant themes. It is an immersive watch that will keep viewers engaged from start to finish. With its strong cast, clever plot twists, and great pacing, this episode is a testament to the show's quality. Fans of Smallville will undoubtedly enjoy this episode, and newcomers will find it a great way to start watching the series.
