'Rookie Blue' Season 6: Andy & Sam Hit A Hitch Before Wedding, Season 7 Still Uncertain [VIDEO]

Andy McNally and Sam Swarek are finally getting ready to tie the knot on ABC’s Rookie Blue but there’s a few hiccups that come up on the season finale.

The sixth season is coming to a close with none other than a ceremony between Andy and Sam. It makes sense considering their relationship hit a huge rough patch after his ex-girlfriend revealed she was pregnant. Now that the child has arrived, Andy and Sam are taking the next step in their own romance. But things turn sour on their big day.

Sam is stoked to “do this thing!” while Andy is MIA. Based on the preview, it doesn’t seem that it’s her fault as she yells at a pickup truck as it takes off, “Come on! It’s my wedding!”

Meanwhile, their Division 15 colleagues are arriving at the venue ready to see the couple say their “I Dos.”

But this could be the final hoorah for the couple and Division 15 as Rookie Blue has yet to be renewed for another season.

In fact, season six was uncertain for awhile. But show runner Tassie Cameron said season seven “is still up in the air.”

“It’s great to hear the networks are interested in keeping us around, it’s such a vote of confidence and means an awful lot. But then there are a lot of things to consider. Theree are the actors and there are contracts…I don’t know…”
