Shiro and Curtis both met in season 7. Curtis worked on the bridge of the Atlas and would refer to Shiro as "Captain" or "Sir". Curtis continued working on the Atlas in season 8 and aided Voltron in their mission. In the episode "Clear Day", Curtis was seen in the audience watching Shiro arm wrestling. He was not visible when Shiro won his arm wrestling competition, and was seen hanging out with the MFE pilots around the same time.
In the ending of season 8, Curtis and Shiro are married, and are shown kissing. The Paladins, Coran, Slav, and others are seen at the ceremony.
Shurtis began to rise after season 8 as the two are now married, though it has faced a large intense backlash within the fandom, and has been criticized by multiple fans and critics who felt the ship was rushed.
It was admitted in the final AfterBuzzTV interview that the entire conceptualization and creation of Shiro's wedding epilogue was added in less than a day, in attempts as an olive branch to the LGBT community. Dos Santos stated, "You know, we, the circumstances at which we sort of arrived at that scene didn’t allow us, we had like a day to really put that together... And we, I think sort of, wholeheartedly accept that it’s clunky. It’s hella clunky."
Not discouraged by this, fans of the ship often contribute works of a happy and healthy marriage or pre-relationship content to fill in the gap of how the ship came to pass. Much of the positive fan work have Shurtis adopting children or animals together. Many fans also have Curtis bonding with Shiro's friends, with some even going out of their way to play matchmaker for them. Another common trope is of the two bonding over mutual grief after losing loved ones in the war.
Due to the lack of background about Curtis, many fans like to create headcanons and speculate on his background. One of the most popular fanons is that he loves dogs, due to his enthusiastic chat with Iverson about his own dog in "The Grudge."
- As per the time skip shown in the epilogue cards, it can be assumed that Shiro and Curtis began to date sometime after the "one year later" scene in the final episode proper.
- Adashurtis refers to the ship between Adam, Shiro, and Curtis
- Curtasheith refers to the ship between Keith, Shiro and Curtis
