On the heels of ordering five additional scripts of veteran Psych in April, USA Network has greenlighted two additional episodes for the dramedy’s upcoming eighth season. That brings the total order for what most likely will be Psych‘s final season to 10 episodes. For one of the extra episodes, USA brass picked among the five extra scripts. For the other, the network is letting fans choose from three episodic storylines. The script for the one that gets the most votes will be produced, with the winning premise getting announced at the Psych Comic-Con panel on July 18 hosted by returning guest star Cary Elwes.

USA originally ordered eight episodes for Season 8 in December, ahead of the show’s delayed seventh season, which did very well. Female lead Maggie Lawson’s ABC pilot Back In The Game was picked up to series, so she will only be available to do up to five episodes of Psych in Season 8. Here are the storylines Psych fans can vote on starting tomorrow:

· TELETHON – In a classic “whodunit?” case with a PSYCH twist, Shawn and Gus investigate a murder that Shawn is convinced was committed by the beloved host of Santa Barbara’s annual Children’s Hospital Telethon. There’s only one problem – the host was seen by hundreds of thousands of people on live television during the exact time the murder occurred elsewhere. Can Shawn steal the show, poke a hole in this rock-solid alibi, and prove the host did it? Or will Shawn fail in front of his biggest audience yet?

· DREAM THERAPY – From acclaimed director James Roday (“Mr. Yin Presents…”, “Heeeeere’s Lassie”), comes a new vision in terror: “Nightmare on State Street!” In the episode, an exhausted Gus enters dream therapy to understand the cause of his recent night terrors. But after this, nothing is ever again what it seems… He soon realizes that in dreams, no one can hear you scream!

· FOOD TRUCK – When the well-known owner of a beloved Santa Barbara food truck is mysteriously murdered, Shawn and Gus, fans of delicious flavor, are determined to solve the crime as only they can. They go undercover as proprietors of the PSYCH Naptime Food Truck, and soon discover that the high-profit world of Santa Barbara’s mobile food business is cutthroat, insular and a place of many secrets – many of them worth killing for.

Panelists at the July 18 Comic-Con event include Roday, Dulé Hill, Corbin Bernsen, Lawson and Timothy Omundson, along with Kirsten Nelson. Also joining the panel are creator and executive producer Steve Franks, and executive producers Chris Henze and Kelly Kulchak. The night before, the show will hold an exclusive midnight screening of the upcoming Psych: The Musical two-hour episode airing this winter on USA
