Kevin and Yvette receive a visit from Dave, one of Yvette's colleagues, who, in his words, wants to join "Team Kevin". Beyond Dave and all her other colleagues having abandoned their mission, Yvette has other reasons for not wanting Dave involved, his help which she eventually but still reluctantly accepts. Through the partial demolition of Amy's house, Kevin discovers that his next mission is to help Susan Allen, Kristin's mother and Kevin's former English teacher. Kevin's mission to help her will not be made any easier as Susan, who has a generally rigid, icy and uptight demeanor, has always had it in for Kevin, that feeling which was made all the worse when he and Kristin started dating in high school. It is also not helped as Dave and Yvette have differing opinions not only on how best to help Susan, but what that end mission regarding Susan is supposed to be. In the process, Kristin, who considers her mother her best friend but the two who are currently on the outs concerning an undisclosed issue, may be collateral damage in Kevin's help exacerbating Kristin and Susan's current issue. Meanwhile, Amy is trying to find some scientific explanation for how Kevin saved Reese when she fell off the beam. She may get a differing "non-scientific" opinion from Ignacio DePerro, a professor in the Theology Department. And Kevin tries to persuade Nate to ask Amy out on a date. What happens in this matter is affected by Reese's surprising thoughts on the matter and the goings-on in Amy's life.
