It's the Season Finale! Ready? Ok!

Wynonna is now Purgatory’s most wanted, so unless she gets out of that venue and quick, she’ll become Purgatory’s most dead.

Meanwhile, Bobo and Willa are making up for lost time / wasting valuable time, just before they cross the border.

Turns out, though, that without Peacemaker in her possession, Willa can’t help Bobo cross the Ghost River Triangle threshold. Foiled!

Officer Haught is initiated into the Black Badge division — it’s been long enough! — and given a sweet gun. Time to turn up the Haught in here.

Desperate for an antidote, townie Chrissy has taken Waverly hostage, and will exchange her for Wynonna’s head.

After Willa and Wynonna rescue Waverly, it’s sister standoff time. Waverly won’t hand over Peacemaker to Willa, and that’s causing a bit of a stir.

Then Officer Haught enters, Willa draws a gun, and the sister-standoff becomes a friendly feud.

Doc and Dolls team up to lay waste to the Revenant scum patronizing Bobo’s bar. And “forget” to leave a tip.

Beset on all sides by antidote-hungry crazies, Wynonna and Waverly find in Sheriff Neadley an unexpected ally. He calls for cooler heads and human decency…and, most importantly, for not killing Wynonna.

Dolls gets shot in the side, and the only thing that can save him is another fix of his special medicine. Doc — that’s his name as well as his one-time profession — plays the pusher man.

Revived and revitalized, Doc and Dolls run train inside Bobo’s bar, retrieve the antidote, and get ready to stop that renegade Revenant as he makes his way out of the Ghost River Triangle.

Dolls’ superiors swoop in on the town of Purgatory to oversee the recovery process. They’ve got new orders: when Bobo opens the gate to Hell, standby.

Well, it’s Willa who crosses over the threshold. And she unleashes something gnarly from the other side.

If she wants to save Purgatory from the jaws of Hell, Wynonna’s got no choice but to lay Willa down. Will she be able to?

Sort of. Dolls ultimately has to pull the first trigger. Then Wynonna puts her sis at peace, with Peacemaker.

Right before Wynonna can do the same to Bobo, Black Badge descends and apprehends the Revenant for further testing. This messes with Wynona’s grand plan to end the family curse. Oh, and Bobo reveals Waverly's not really an Earp. WTF?

Fortunately, Wynonna’s such a keen shot, she’s able to nail Bobo sitting on the back of the Black Badge truck from nearly a quarter of a mile away. Bang, baby.

At the site where her sister perished, Waverly finds a puddle of some thick black substance that was ejected after the tentacled monster scooped Willa up. And, like all puddles of a thick black substance, it demanded she touch it. She did and then her eyes went all black. And then? She pulled a gun out on Wynonna. Shots fired?
