After seasons of turmoil, things are good for Dawson (Monica Raymund) and Casey (Jesse Spencer) on Chicago Fire—in fact, they're so good that the couple might take their relationship to another level.

"Casey and I are now really committed to each other and we feel like we're family, and I think we're going to see some really amazing stories from the both of them," Raymund told E! News at the One Chicago celebration last week. In fact, after five seasons, your favorite couple might be in the best place they've ever been.

"We actually make a commitment to each other in a way that I think the fans will be very excited about," she confesses.

Hm, could that mean wedding bells will ring soon?

Before that happens, however, Dawson will have to get used to her new (old) job—"Being back on ambo is like being back home. And I love, love Kara Killmer," Raymund says—and continue to raise her foster son, Louie.

"He's so cute! So pensive, so worried about everything. He's adorable, and so you're seeing him become more loquacious and his personality is developing," she says.

Plus: bonus footage of Raymund's castmates proving they're just like you—they also think she's a gorgeous goddess who should be worshipped and rocks the heck out of a red occasion dresses.

In other Firehouse 51 news, Yuri Sardarov told E! News that he has an idea for another new spinoff: Mars Fire.

Yes, you're scratching your head, but trust him: it totally makes sense, since Otis' new adventure will involve training for a very important mission to space. "Cruz has been helping him create his resume and build up his lung endurance and they're a team on this thing together," Sardarov explained.

He also dished on Otis' dating life (while you might not see it on screen, trust that Otis is swiping away on the best dating apps Chicago has to offer) and why he wants Otis' fling from the bar, Natasha (Lauran September), to return for more episodes."We had this thing at the bar, she spoke Russian, she was a total nerd, we hit it off. I hope they bring her back!"
