'Chicago P.D.' finale: Who shot [spoiler]?

Spoiler alert: If you haven’t watched the Chicago P.D. season finale, stop reading now!

In the world of Chicago P.D. nothing is black and white. After all, the man at the head of the Intelligence Unit was in prison not all that long ago. But could he be going back?

That’s the question that fans are pondering after the final 30 seconds of that finale, in which Voight walked onto a crime scene that housed Jin’s dead body. Jin. As in a member of Voight’s Intelligence Unit. As in a member of this family we’ve come to love. And as in the (lovable) rat who’d been reporting to Internal Affairs all season, a fact that Voight had earned just half an hour earlier. So had Voight pulled the trigger and killed his own man? My gut tells me no. Voight has a thing with killing cops, and at the end of the day, he did love Jin. Then again, wouldn’t that make for an interesting season 2? R.I.P. Jin. I’ll miss your weekly bursts of brilliance.

Other big developments you need to know about: The shady hottie from Lindsay’s past, Charlie, tried to threaten her with a deep dark secret — her friend Annie had committed murder in 2002 and she had helped hide the body — but he clearly didn’t understand the code of the Intelligence Unit. They don’t dwell on the past. They forgive. And, if their names are Lindsay and Halstead, they have crazy ridiculous sexual tension. Was it too much to ask for even a hug at the end of the hour? Fine, I’ll just dwell in the look on Halstead’s face when Charlie threatened Lindsay. I do love a defensive man.

By hour’s end, Linstead had won. Charlie confessed, Lindsay saved her partner’s life — did anyone else panic in that moment thinking #HotHalstead was a goner?! — and they went back to shooting sex eyes at each other at the police station. Here’s to hoping Charlie takes proper care of his hair in jail. It’s called priorities, guys.

Moving to the show’s other romantic entanglements, let’s start with the bad news: Antonio went back to work a little bit earlier than his wife would’ve liked him to, so they spent the entire episode arguing on the phone. And when he went home at the end of the day, she’d left him. OK, can we talk about this? Your husband goes back to work too soon after being injured on the job and you take the kids and leave him? I’ve never been married before, but I think it’s fair to say that was an over-reaction.

Now to the good news! Burgess and Ruzek finally gave in to their many feels for each other! After a day of having to prove herself on the job — thanks to her recent romantic entanglements — Burgess went home to make some pasta-for-one (out of a can!) when a very handsome man knocked on her door. He wanted to apologize for making her work-life harder, but the bottom line was that he couldn’t stop thinking about her. Cue the make-out, the (sort of unnecessary) pick-up, the undressing, and the implied horizontal mambo/salsa.

I might have cheered when this happened, and then I might have watched it two more times. So the real question is: What are we calling them? Burzek? That doesn’t quite roll off the tongue. Suggestions needed!

Elsewhere, Atwater was still trying to prove himself to the team, and Olinsky was rocking yet another beanie better than anyone else on TV.

All in all, I thought it was a great end to a season that I’ve unexpectedly fallen in love with. I didn’t think I’d get into this show, but now, it’s safe to say I’m all in. And I already miss Jin. And I don’t know how to feel about Voight. Also, I want more Linstead and Burzek. Stop me now or I’ll keep going. What did you all think of the finale?
