Ever since Nick Collins (Peter Mooney) joined the 15 Division as a rookie a few years late — season 3 to be exact — he’s been a bit of a mystery. Sure, we know he was in Afghanistan; we know he was engaged to marry Gail Peck (Charlotte Sullivan); and we know that later he went undercover and started dating Andy McNally (Missy Peregrym). But otherwise Nick Collins hasn’t received much of a backstory…. until now.
“Letting Go,” Thursday’s episode of Rookie Blue is “a big one for Nick,” according to Mooney. “We’ve dropped a few crumbs along the way about his past, what happened in his life before Afghanistan and before he was a rookie — this is where it all comes rushing out.”
And what causes that to come rushing out is Nick’s estranged brother showing up. Nick has been extremely guarded about his background — the events of this episode will shed light onto why — so his brother being around isn’t good for him. “It bleeds into his personal life and into his professional life, which throws him into a real tailspin,” Mooney says.
What makes the story more complicated is newbie Juliet Ward’s (Erin Karpluk) involvement. Mooney says she’s going to find out more about him, and vice versa, which puts their will-they/won’t-they relationship into question. More importantly — Nick might finally see how suspicious it is that Juliet is at the 15 Division. “He doesn’t get all the insights the audience gets, so I give him a bit of a break,” Mooney says with a laugh. “But he’s missing some big clues.”
As for getting to finally explore Nick’s origins, Mooney is “thrilled” and has been waiting a long time for it: “It’s a story that I talked about with [EP] Tassie [Cameron] from the very beginning; some of the elements of the story haven’t played out yet,” he says. “It was great to have it all come out in one big ole’ shotgun blast.”
Rookie Blue airs on Thursdays at 10 p.m. ET on ABC.
