Barney proves to Nora that he can be a good boyfriend to her, while Robin is revealed to still have feelings for Barney. Robin takes court-mandated therapy, until her therapist Kevin (Kal Penn) says he finds her attractive and therefore cannot be her therapist anymore. They start to date.
While reminiscing about Hurricane Irene, Barney and Robin end up sleeping together. Barney and Robin both realize what they've done and decide to break up with their partners. However, Robin decides to stay with Kevin, which devastates Barney, who did break up with Nora. Marshall and Lily decide they want to move to Long Island, after Lily's paternal grandparents offer them their house there.
Robin gets a pregnancy scare. Going to the doctor, she learns that she cannot have children, which devastates her. Kevin proposes to Robin, while she knows she loves him and that she is ready for the commitment, she tells him she can't have children and that she doesn't want kids at all, so they break up. Soon after, Robin tells everything that happened to Ted, only for him to profess his love for her (which is revealed to be the final time he declares his love for someone other than his future wife). Robin soon admits that she does not love Ted, and Marshall asks her to move out of Ted's apartment so that Ted can finally move on in his love life. Ted then gives his apartment back to Lily and Marshall, because he feels he and Robin haunt that place.
Barney starts dating a stripper called Quinn. Soon it is decided that Quinn will move in with Barney, and Ted moves into Quinn's place. Soon after this, Robin is asked to deliver a traffic report from the World Wide News helicopter.
