This is it, Motive fans. The penultimate episode is upon us. It’s been one hell of a ride, hasn’t it? We’ve loved this four-season peek into the lives of Angie Flynn, Oscar Vega, Betty Rogers and Brian Lucas. They’ve solved crimes, faced adversity and enjoyed copious adult beverages together. But before the final farewell—will Angie move to Paris?—we’ve still got this week’s story to cover.

Here’s what CTV has to say about “Chronology of Pain”:

When Detective Angie Flynn (Kristin Lehman) and the team investigate an explosion at Judge Natalie Rodman’s (Joanna Cassidy, CALL ME FITZ) home, Angie is grateful her mentor survived. But when the Judge dies a short while later, Angie races to catch a sophisticated killer who’s an expert at covering their tracks—and may strike again.

And here’s what we can tell you after previewing the episode, written by Julie Puckrin:

Angie as … staff sergeant?
She may be a fill-in for now and says she’s not interested in the gig, but is Angie telling the truth? Her thoughts on her years as a detective, and possible next steps, are challenged when Judge Rodman is found dead.

Kennecki returns!
We’ve certainly missed the wise-cracked, over-confident cop, haven’t you? Thankfully, we get a dose of Det. Mitch when Angie investigates the incident at the judge’s house. The two have a nice little tête-à-tête that hints Angie could be one heck of a mentor.

A.J. Buckley returns to TV!
Oh, how we’ve missed Buckley on Canadian TV. The former CSI: NY forensics expert checks in to Motive as a car mechanic who is key to the case.

Motive gets vice-presidential
OK, he played a vice president on The West Wing, but we were giddy to see Tim Matheson guesting as Brent, the judge’s husband. Sure, he seems worried about his wife’s well-being, but did he have reason to off her?
