Global’s “9-1-1” could get a lot more steamy.

Following the hit series’ announcement that Connie Britton would return for a few episodes in season three, star Oliver Stark is teasing a possible reunion between his and Britton’s characters, Buck and Abby.

“I think it’s really hard,” Stark explained to TVLine during the Television Critics Association winter press tour. “So many people in that first season fell in love with the relationship between Buck and Abby, so she was really hard to replace.

He added, “And Buck has had so much growth since then. [Moving forward, it will be] about finding the right partner for him. A lot of people have different ideas about who that could be, whether they’re on the show already. I don’t know what [Abby’s return] means. I don’t know what that’s going to stir up. But it’s teasing at stuff, which is always fun.”

Stark had previously chatted with fans about Buck’s character development, even the possibility of being romantically involved with Eddie (played by Ryan Guzman), lovingly nicknamed “Buddie” by fans.

“I don’t know where the story is going,” Stark recently told fans on Twitter. “I have always spoken openly about how amazing I think it is that you are invested in [Buck and Eddie], and I totally support that. But I feel uneasy about RT’ing stuff, because I know it can sometimes come across as me confirming something is going to happen. I don’t want to get anyone’s hopes up.”

“9-1-1” returns in March on Global.
