Season 8: Episode 19 - The Fortress

The Fortress: Robin gets Barney to reluctantly agree to sell his apartment in order to start their marriage together in a home with a clean slate. At the open house, Barney drives away prospective buyers by showing them the amenities he installed to trick women into sleeping with him, but a couple opts to buy the apartment anyway. When Robin discovers that the couple plans to completely gut the apartment, she reneges on the offer and decides to move in after realizing her appreciation for all aspects of Barney. Meanwhile, Lily’s commitment to her new job as The Captain’s art consultant places a strain on her relationship with Marshall. They reach a compromise when Lily sets boundaries for The Captain’s demands while Marshall agrees to be more supportive of Lily’s career. Also, with Lily gone all the time, Marshall and Ted watch their favorite show “Woodworthy Manor” without her.
