Stella says "yes" to Ted's proposal. Robin takes a new job in Japan, but quickly resigns, returning to New York to attend Ted's wedding. Stella leaves Ted at the altar to get back together with the father of her daughter, Tony. Barney struggles with his feelings for Robin as his company shifts him to the management team of a new acquisition, Goliath National Bank (GNB).
Marshall and Lily move to their new apartment and debate over whether or not they're ready to have children. Robin becomes roommates with Ted and gets a job as an anchor for a 4:00 A.M. news show after Barney sends out her video resume. Ted finds out about Barney's feelings for Robin when Ted and Robin sleep together constantly so they won't fight over each others bad co-living habits.

Ted is asked to design the new GNB headquarters but he is fired after the plans for the new building is scrapped. Because of this, Ted loses his job and then starts his own company, Mosbius Designs.

Ted finds out Lily has sabotaged all of his relationships with anyone she doesn't approve of and indirectly may have inspired his breakup with Robin. Robin and Ted end up talking about it, causing their friendship to begin moving towards a positive note. As Barney finally sleeps with his 200th woman, after rubbing it in the face of the childhood bully that taunted him into pursuing it, he questions what the rest of his life would be about now, leaving him more certain of his feelings for Robin.

Ted, while carrying the yellow umbrella, bumps into Stella and Tony. Tony later decides to visit him, sympathizing with Ted over his loss of Stella. Tony offers him a job as a professor of architecture, which Ted initially turns down. Lily abandons the group and disappears for four weeks after hearing a dirty joke from Barney.

In the season finale, Robin finds out about Barney's love for her, which she cautiously reciprocates. Ted decides he is done being an architect and finally decides to instead teach architecture classes. The finale ends with Ted stating that the mother was in the first class he went into.
