How I Met Your Mother Episode 9.17 Sunrise

Barney is drunk13 hours before the wedding, wanders out of the Inn and goes missing. He bumps into two young men and teaches them "to live" - ie: suit up and go to strip clubs - and at the end, bequeaths them the pages of the Playbook. We learn that a few days earlier, Ted traveled to Los Angeles to find Stella, his ex-fiancee, in the hopes that she had Robin's locket that she wants for her "Something Old." In present day, Robin and Ted walk on the beach and discuss why Ted and Victoria broke up - it was over Ted's friendship with Robin. We learn that when Ted found out Stella didn't have Robin's locket, he called Victoria, who sent it to Ted, but it was intercepted by Jeanette, Ted's crazy ex. Marshall reasons with "ghost Lily" about the fight they just had, only to have "the ghost of seven years ago Lily" also appear. Ted and Robin have an honest conversation where Ted tells her that Robin is his number one, and he's only telling her because it won't make a difference - he's moving to Chicago after the wedding.
