Missy Peregrym in 'Rookie Blue'

Six television seasons into being a police officer, it’s debatable whether you’re a rookie anymore.

With that said, the cops of “Rookie Blue” always are discovering something new – personally as well as professionally – and that’s destined to stay the case as the sixth season of the Canadian-made drama starts its ABC run Thursday (June 25). As they were in 2014, the new episodes are being shown a month earlier in their native country, but spoilers for U.S. audiences were remarkably sparse last summer.

“We were pretty careful about that,” Missy Peregrym, alias the series’ Officer Andy McNally, tells Zap2it. “It was a little weird doing press, because I didn’t want to say anything that would spoil it for America, either. We didn’t really respond to a lot of stuff or put things out there, just so all the fans could enjoy it at the time they were able to see it.”

Having emerged from an explosion at the 15 Division precinct shaken but relatively unscathed, Andy now faces a fresh emotional crisis. After reuniting romantically with Detective Sam Swarek (Ben Bass) following his near-fatal shooting, she learns he’s expecting a baby with fellow officer Marlo Cruz (Rachael Ancheril), who was Sam’s flame while he and Andy had broken off their relationship.

“It is obviously very difficult,” confirms Peregrym. “Things are starting to look up (for Andy and Sam), so we’ve gotta smack it down with something.” The actress had input into how that went down: “I love our team so much, because I have the freedom to go and talk to somebody and say, ‘I’m sorry, but this is how I feel like this would really go down. Can we work this out?’ They’re so open to that.”

Another major “Rookie Blue” plot this season suggests last season’s police-station bombing may have been, at least partly, an inside job.

“You don’t know who to trust anymore,” Peregrym reflects. “Last season, the dynamic between Andy and Matt Gordon’s character [Staff Sergeant Oliver Shaw] got roughed up; he was like the father figure to her, but their positions are changing, so what does that mean for their working together? Matt’s such a great actor. He always brings so much to the table, and that extends into this season as well.”

With co-star Gregory Smith (the series’ Officer Dov Epstein) again directing two episodes, Season 6 of “Rookie Blue” actually is the back half of a “super-season” the cast and crew filmed through much of last year, beginning with the stories that comprised Season 5.

Traditionally, it’s taken only a few weeks into a new season to learn if ABC will give the show another one, and Peregrym hopes that will be the case again. Even if it does return, a key behind-the-scenes player will be absent, since executive producer and co-creator Tassie Cameron is moving on.

“It’d be easier for us if we knew a little bit sooner, but at the end of the day, I can’t believe we’ve even gone this long,” Peregrym says. “It’s such a blessing that we’ve been able to work together for so long, and honestly, I think Season 6 is even stronger than Season 5. The characters go through a lot of really great things, but who knows? We’ll see what happens next.”
