Ep 8. A Touch of Sweevil

In Psych season 8 episode 8, titled "A Touch of Sweevil," Shawn Spencer (played by James Roday) and Burton "Gus" Guster (played by Dulé Hill) take on a case involving a pharmaceutical company. The company, called Relevium, has been in the news recently due to a string of deaths related to one of their drugs. The company's CEO, a man named Jerry Kincaid (played by Tony Hale), becomes the main suspect when one of his employees dies after ingesting the drug.

Shawn and Gus are hired by Kincaid to prove his innocence. However, they soon realize that the case is more complicated than it seems. As they dig deeper, they discover that there may be a conspiracy at the heart of the company, and that someone may be trying to cover up the dangerous side effects of the drug.

To make matters worse, Shawn is dealing with his own personal dilemma. He has been having recurring nightmares about a villainous character from his childhood television show called Mr. Yang (played by Ally Sheedy), who also happens to be a serial killer. He is convinced that Mr. Yang is somehow connected to the case and is determined to unravel the mystery.

As they investigate, Shawn and Gus encounter a host of eccentric characters, including a Relevium employee who likes to wear a hazmat suit, a janitor who is surprisingly knowledgeable about chemistry, and a beleaguered FDA agent who is trying to keep up with the case.

As always, the comedy in the episode comes from Shawn and Gus's banter and antics. There are plenty of pop culture references, ridiculous disguises, and over-the-top reactions to keep fans of the show entertained. However, there are also moments of genuine suspense and intrigue as the duo gets closer to the truth.

Overall, "A Touch of Sweevil" is a solid episode of Psych that will please fans of the show. While it may not be the most memorable episode of the series, it is a fun and enjoyable mystery with plenty of laughs and a few surprising twists.
