The official synopsis of the episode mentions: "Stewie is given drugs for his ADD and Brian uses them to pen an epic 2000-page pitch to author George R.R. Martin at a book convention. Meanwhile, Quagmire and Peter engage in an Iron Chef-style competition to see who gets to keep his new cooking show."

According to IGN, the focus of the latest episode will be on schoolchildren on over medication. Stewie is addicted to ADD and once he brings Brian, it is chaos beyond imagination.

After taking the drugs, Brian becomes hyperactive. Once, finished with his massive pitch to the author George Martin, both Stewie and Brian decide to go to Hartford. However, it seems Martin is not very pleased with the story idea sent by Brian and turns it down.

Besides, episode 2 also showcased the old characters of Quagmire, Joe, Cleveland and Peter. Quagmire and Peter take part in an Iron-chef style contest, though the winner is yet to be confirmed.

We had reported earlier that a number of celebrities are all set to make an appearance in the latest season, including Ashton Kutcher, Neil DeGrasse Tyson, Ed O'Neill, Kyle Chandler, Margaret Cho, John Mellancamp, Jeff Garlin and Kathryn Hahn.

Kutcher's wife, Mila Kunis, plays the role of Meg Griffin in the show and fans are excited to find out whether the two will interact to each other while Kutcher makes the appearance. However, there has been no confirmation from the producers yet.

Peter's sister, Heavy Blow, is also set to appear in one of the episodes. Voiced by Kate McKinnon of "Saturday Night Live" fame, Heavy Blow is a professional wrestler and doesn't hesitate for a second to punch the air out of anyone.
