“Twelfth Night” is a comedy, so it calls for a happy ending — but not all of the play’s characters get a wedding and a ride off into the Illyrian sunset. Amid all the the farce and revelry of “Twelfth Night,” Malvolio’s story is a darker one. Featuring interviews with Amin El Gamal (“Prison Break,” “The Newsroom”) and UCLA English department chair Lowell Gallagher, this episode takes a closer look at why Malvolio fantasies about marrying Olivia, varying views on what Malvolio’s revenge might be, and how a problem we can see Shakespeare thinking through with Malvolio is ultimately solved in “Hamlet.” And, of course, what’s up with those cross-gartered yellow stockings.
