Jo Wilson (Camilla Luddington) and Atticus "Link" Lincoln (Chris Carmack) share one of the best friendships the latest seasons of Grey's Anatomy have produced, but the show may have hinted at something more between them with season 18 episode 7's newly released trailer. When Link had started at Grey Sloan Memorial Hospital in season 15 and had met Jo by chance, their reunion was as surprising as it was joyful. Throughout the last three seasons, viewers have seen Jo and Link being there for each other unwaveringly, through thick and thin.
When Jo came back home devastated from meeting her biological mother, it was Link that knew how to support her. He did not try to make her get better, and he did not try to get her to do things; he was just there, with her at her and Alex's house, doing her laundry and being there for her. When Link and Amelia broke up as he wanted to marry her while she didn't, he went to stay with Jo, the two of them caring for their respective children, Scout and Luna.
Their profound friendship has been one of the cheeriest things to come out of the most recent seasons of Grey's Anatomy, and in the past, there were rumors they could have become an item. At the time, Jo had just been left by Alex and was single, while Link was having problems with Amelia as she had told him their baby might not be his. Amelia and Link's relationship then went on, but with it now over, and with Grey's Anatomy season 18, episode 7's trailer showing Link revealing to Jo that he had a crush on her, things might evolve differently, leading to their perfect ending.
A potential romantic relationship between the two would make sense, not only for how important they have always been for each other but also because they seem to both truly want a family. Jo and Link share a similar path in becoming parents: they were against it at first, terrified by everything that could have gone wrong. After talking it out with their partners at the time, they became more accustomed to the idea, and when they met their newborns, they realized how much they loved them and would have been there for them.
Jo and Link were ready to start a family with their partners, but with Amelia leaving Link and with Alex choosing his family with Izzie over Jo, at the start of Grey’s Anatomy season 18, they were both left abruptly to deal with the reality they could not share that part of life with their chosen partners. The two of them have been grappling with the struggles of being single parents that work and have a lot on their plate at the moment. Nevertheless, Jo and Link's potential romantic relationship would lay its foundations on the already deep bond they share and could definitely be the one relationship that ends up working for both of them along with their happily ever after.
