In 1923's Yellowstone, the love story between Spencer and Alex takes center stage. This year is the most romantic period explored in the Taylor Sheridan universe. The couple's whirlwind romance unfolds throughout the series, and in Episode 6, their love truly blossoms. Spencer convinces Alex to join him on a chartered tugboat journey to the Suez Canal. However, their plans go awry when their captain passes away, and the boat becomes immobile. Stranded on an abandoned ghost ship, they fear for their lives. Despite the dire circumstances, their love for each other only intensifies.

Fortunately, they are eventually rescued by a passing ship. It is then revealed that Alex will have difficulty entering the United States as a single woman without a husband to sponsor her. In a surprising turn of events, Spencer proposes marriage to the ship's captain. Though it is against the law to marry for immigration purposes, Spencer assures the captain that his intentions are genuine. The captain presents a box of rings for the couple to choose from, even offering Spencer's own wedding ring when they can't find the perfect fit. As their wedding takes place, the parallel romance between Spencer's nephew Jack and Elizabeth unfolds, adding to the overall theme of young love within the Dutton family.
