"So this is what the inside of Salvador Dali's head looks like," is how Simon describes Harken's office—with desks askew and the floor and walls splattered with various different paints.
And then Harken completely stumps everyone except Isaac by giving them a moral dilemma with only the barest information given to them: "burn it or drown it?" Isaac answers correctly with "Burn it and then drown it." and Harken reveals the dilemma was about a Zombie Apocalypse.
Basically, the entire arc involving Isaac hooking up with Tala and Wendy, one of the forum's crowning examples of Refuge in Audacity. First, he accidentally stumbles across them having sex in the library, prompting Tala to hold a gun to his head, threatening to kill him. In the last seconds, he begs for his life, and...a "Bang!" flag comes out of the gun. Tala playfully kisses him on the cheek and sends him off on his way—though he's completely traumatized and decides to talk it over with Magi. His solution? Associate the sight of her naked with a more positive memory; namely, having sex with her. Then Isaac comes up with a clever idea: age himself up to age 16 using one of Timmy's devices and have sex with Tala to associate her with a more positive memory. Which he does, and all is well.
While having breakfast with Gill and Adrian, Willow briefly gets up to have a conversation with Tripp. Adrian takes the opportunity to enjoy theeye candy; he turns to Gill, saying, "I never really noticed until now, but that telepath girl, Willow? Hawt." It becomes hilariously awkward for Gill, who is revealed about a minute later to be one of Willow's ancestors.
