A Vineyard Valentine

S6 E15: As Valentine's Day approaches, Rory and Logan invite Lorelai and Luke to spend a weekend with them at Logan's family house on Martha's Vineyard. Rory and Logan have a wonderful time, but Lorelai is upset by Luke's unfriendly attitude towards Logan. Luke's attitude changes when he realizes he forgot to buy Lorelai a Valentine gift, and Logan saves the day by letting Luke give Lorelai one of the gifts he had bought for Rory. When Lorelai finally confesses to Luke that she is worried the wedding will never take place, he reassures her that they will get married soon. The weekend ends in an ugly scene when Logan's father, Mitchum Huntzberger (recurring guest star GREGG HENRY), arrives and berates Logan for ignoring his responsibilities in the family business.
