A couple that kills together, stays together. And on The Walking Dead, Rick Grimes (Andrew Lincoln) and Michonne (Danai Gurira) certainly both did that.

These two were as deadly to the dead as they were in love, though their romance came to a tragic end when Rick detonated explosives on a bridge to prevent a horde of walkers from reaching their people. Presumably, in the eyes of his friends and family, he died in the process. What Michonne didn’t know—and still doesn’t know, not for sure—is that Rick survived and was taken by helicopter to the mysterious CRM. After years of grief and searching, when she found evidence that Rick might still be alive, she began an epic quest.

Will Michonne’s search for the love of her life see them reunited? Will their romance survive the years of separation? In the upcoming “Richonne”-centric limited series The Ones Who Live, we’ll likely get the answers to those questions. For now, we’re taking a look back at the couple’s steamiest, heartwarming, and heartbreaking moments from the main show.
