* Mark's FinalBattle with Graham: he confronts Edwina and [[GrowingASpine makes her]] [[MistreatmentInducedBetrayal join their side]], he manages to take photos of evidence about Graham trying to cover up [[spoiler: the failures of his experiments and made-up results]] while Graham tries to [[MoralEventHorizon beat him up]], easily rebuffing his [[SmugSnake confident]] "why would they believe you?" by spelling these out to him, topped with "why ''wouldn't'' they believe us?", as well as spelling out the danger his career is in when he haughtily refuses being bossed around by a student because he is a [[SmallNameBigEgo renowned scientist]]. After breaking through his [[TooDumbToLive overconfident obliviousness]] of the danger he is in, Mark blackmails him into dropping all charges against Alex, and Ian offhandedly adds: "oh, and make sure Edwina gets another advisor". Because he saw her always drop a penny into the donation box in the cafeteria.
* If Mark's friendship with Penny is doing well by the end, he goes into business with her when one of her apps makes it big. Even more awesome if you've romanced Phil, as his path includes a scene earlier where Penny tries to talk to an established app designer and gets rudely brushed off.
