Barney and Quinn take the next step and move in together, but when Barney is unwilling to get rid of any of his old possessions, the gang suspects he thinks his relationship with Quinn won't last. Meanwhile, Ted, Marshall, and Barney embark on another trilogy time, the three year event where they get together to watch the Star Wars trilogy and envision what their lives will be like in another three years. While Ted and Marshall have always envisioned successful careers and marriages, Barney's fantasy has remained the same: a new girl, a new opportunity to have sex. However, this year Barney realizes he wants to be with Quinn in three years. Meanwhile, Ted loses hope that 2015 will be any better for him...until a flash forward reveals that in three years he will, in fact, have a newborn and be with the mystery mother of his children.
