Fans are waiting for the anticipated Season 4 premier of "Chicago Fire" after the third season's finale ended in a shocking cliffhanger.

Casey (Jesse Spence) and Dawson (Monica Raymund) will not be the only love birds in the house for Season 4. Serveride's love life will make a big turn even though things between him and the Med doctor did not work out in the last season, TVLine reports.

"There's going to probably be an in-house romance for him," executive producer Matt Olmstead reveals. "We want to give him something a little more substantial. A real love interest."

In the Season 3 finale, Dawson took a pregnancy test but the camera never showed her results. She rushed over to tell Casey the news only to find his stripper friend dead on the floor while he went MIA.

It's speculated that Dawson is pregnant because why else would she rush over to give Casey the news? Casey may also be involved in the death of the stripper because he went missing around the time her body was found.

Some hints from the murder case could be shown in the show's spinoff "Chicago P.D." ahead of "Fire's" Season 4 premier in the fall, CarterMatt reports.

Viewers may also be able to find out a little more about Brett and Roman's relationship on P.D.

Showrunners are working on a plot for Season 4 where people would find out where Casey and Dawson's relationship is headed, according to The Hollywood Reporter.

"There are a couple scenarios we are actively debating in the room right now," executive producer Matt Olmstead says. "But the stone that we dropped in the pond so to speak at the end of the season -- the mere fact that we're in the room having a robust discussion about what those ramifications could be was a good sign that we're on to something."

Season 4 of "Chicago Fire" is set to start in November.
