WARNING: This article contains major spoilers for "There Will Be Blood," the latest episode of The Flash Season 6.

In last week's episode of The Flash, Ralph Dibny put his private-investigator skills to good use when his mother was accused of theft. While he was able to clear her of the crime, the case revealed that Ralph's mother had been keeping the truth about the end of her relationships from him. When the two eventually patched things up, Debbie urged her son to take his own advice and finally open himself up to finding true love. All signs seemed to indicate that Ralph was ready to take that big step.

This emotional breakthrough in the Elongated Man's character arc raised the possibility that The Flash was getting ready to introduce Sue Dibny, Ralph's wife in the comics. There, Ralph and Sue are among the DC Universe's most beloved couples, the kind of relationship every superhero aspires to have.

However, it now appears it's no longer a theory. In this week's epsiode, Sue is not only mentioned by name, Ralph embarks upon a collision course with the woman he's fated to marry.

In "There Will Be Blood,' Ralph loses faith in his ability to be hero and make a difference following the heartbreaking news that Barry Allen will die in the upcoming "Crisis on Infinite Earths." As he wrestles with the looming the loss of a good friend, Ralph is approached by Iris, who reveals she has gotten a lead in his missing person's case. As viewers might recall, at the end of Season 5, Ralph traveled to Opal City to investigate the whereabouts of a person named Dearbon. That's Sue's maiden name.

He returned to Central City in Season 6, having spent all summer looking for Sue, but to no avail. Now, in "There Will Be Blood," a lead finally appears. The only problem is that Ralph has no intention of following up on it, given the recent revelations about the coming crisis. However, thanks to a push from Iris, Ralph once again finds his heroic drive and decides to pursue the case.

As the episode ends, Ralph is set to visit Midway City, the location of his next lead. And in case there was ever any doubt that Ralph is about to meet the love of his life, before leaving, the private investigator tells a pleased Iris that it's only a missing persons case; he's not looking to get married or anything. The line is clearly meant as a nod to the character's future relationship with Sue.

Now, it seems all but certain that The Flash will introduce Sue Dearbon to the Arrowverse. And if the comics are any indication, fans will then be treated to an epic love story capable of inspiring the world's best superheroes.

Airing Tuesdays at 8 p.m. on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanagh, Jesse L. Martin, Danielle Nicolet and Hartley Sawyer.
