If Psych‘s upcoming eighth season turns out to be its last, USA Network’s long-running laugh-riot is going out with a bang.

Series creator Steve Franks, who dropped by TVLine’s Comic-Con interview suite with series stars James Roday and Dulé Hill, confirmed to me that the show is heading to London for an episode inspired by Harry Potter — but there’s a twist (actually two twists): The show isn’t literally going to London. And Psych‘s take on Potter will feature a, ahem, “Guy Richie gangster” element, per Franks.

Press PLAY below for more on that episode, as well scoop on the “creative” way producers are working around Maggie Lawson’s new scheduling conflict and the latest on the possibly-imminent series finale. Oh, and you’ll also get proof Dulé is the biggest spoiler whore in all the land — yep, even bigger than yours truly.
