Lindsay reluctantly leaves Gus with Brian while she goes out of town for a conference. David's 12-year-old son Hank comes for a visit that David has planned down to the very minute. Jack tells Brian he has cancer and only has a few more months. Hank ... (more)tells Michael he didn't want to visit, that he's only here because his mother made him. Debbie advises Brian to be honest with his father before he dies. Brian leaves Gus with Justin so he can go to the Leather Ball at Babylon, a move that will earn him angry castigations from both Melanie and Lindsay. Ted discovers that a former business school classmate is an award-winning "Leather Daddy" whose house includes a dungeon-themed playroom. Ted refuses Dale's proposal to be his "slave." Michael thinks Hank hates visiting his father because he's gay, but it's really because of David's itineraries and over-planning. The two end up bonding over a mutual love for comic books.
