Criminal Minds ends its 13th season with back-to-back episodes and a finale cliffhanger. First, in episode 21, "Mixed Signals," the team heads to New Mexico to investigate an UnSub who is targeting his victims' temporal lobes.

Then in episode 22, "Believer," when Reid finds former FBI Special Agent Owen Quinn locked inside a storage unit, the BAU questions the credibility of Quinn's bizarre accounts of searching for an UnSub he named "The Strangler."

Find out more about the victims from the case of "Mixed Signals":



Stacy was a family physician, married with no kids. She was born and raised in Taos and returned after medical school. Steve moved there as an adult, is (amicably) divorced and a high school history teacher. They didn't run in the same social circles and both were well-liked.

It's when a third victim is found that they find a possibly connection. Ben, a construction worker, was born and raised on a nearby reservation but lived in town with his wife and three-year-old daughter. Stacy also had Native American blood, and Steve developed an in-depth and controversial course on Native American living histories that wasn't popular with the administration or parts of the community.

The UnSub left a victim alive in this sneak peek:



The UnSub followed Alma Hernandez out of the library and threw her against a car, but he didn't kill her. Why? Was it too public? Did he need more time? Chief Carlsen tells them that she's deaf and their sign interpreter isn't there yet, but Luke can sign.

Find out who Owen Quinn is in this clip from "Believer":



Quinn worked in the Violent Crimes Apprehension Program, but he wanted to be a profiler. He was convinced there was an UnSub they missed and called him "The Strangler" -- but naming him wasn't his only mistake.

He started with a single victim, a woman in Maryland who'd been strangled and had the hyoid bone at the front of her throat removed, but she was the only confirmed victim. He started forcing missing persons into the victimology to fit his profile, but in the end, five of seven potential victims turned up alive and unharmed. The other two were inconclusive.

Quinn took the criticism personally and quit. He said he'd pursue the investigation on his own.

How did they find him in the storage unit? Reid got an email from an anonymous sender. But he hates email, J.J. notes. The email included Quinn's FBI ID badge, a big piece of bait the UnSub had to know they had to take. But did the UnSub think Quinn was dead when he left him there for them?

Is Reid keeping secrets again? Watch this clip:



J.J. wants Reid to tell her not to be worried. Why did he take a SWAT team to the storage unit in the middle of the night instead of calling the rest of them? Last time he kept secrets, he went to prison for a murder he didn't commit.

Whoever did this wanted him to find Quinn, Reid explains, and he needed to know why. He had only seen Owen in the building occasionally, which made it weirder. He went to Prentiss, she made it happen, and that's everything. But is it?

Do you think Reid has told J.J. everything? Comment below with what you think is going on with Quinn and how you think the finale will end.

The two-hour Criminal Minds season 13 finale airs Wednesday at 9/8c on CBS. Want more news? Like our Criminal Minds Facebook page.
