In Undiscovered Country, he completes the metamorphosis.

Its a good thing shes there, too, because Tufo cant remember proper CPR procedure.

How are any of these people still employed?

An ambulance arrives, and Harlee clambers in.

Meanwhile, Tufo collects a shocked, sniveling Tiffany.

(This plan seems destined to fail phone records are very easy to check these days.)

Woz is waiting at the hospital when Harlee arrives.

Sap is immediately wheeled into surgery, and once the room is clear, Harlee rounds on her lieutenant.

Surprisingly, shes already come to the correct conclusion.

Shes not quite willing to bring her theory to the rest of the crew yet, though.

Once hes out from under her watching eyes, he asks a doctor about Saps condition.

He could remember everything, or he could be a vegetable.

They retrace Harlees steps back to her visit with Zepeda.

After last weeks attempted murder, Im okay with that.

Tufo:9 out of 10, Super Guilty

What is with this squads love of sexual violence?

Tufos near-rape of Sofia is just the icing on this morally compromised cake.

When questioned, she says she only heard about Ritas demise secondhand, but Stahl knows better.

He whips out a recording of her calling the police to report Ritas stabbing.

For his final exhibit, he also hands her a photo of Kovach.

The friend says she doesnt recognize him, but Stahl senses shes lying again.

He begins to put the pieces together: Kovach was Ritas real killer, not Zepeda.

Who do they know whos related to both men?

Stahl is on a roll now, and hes inching closer to uncovering Harlees part in her exs conviction.

NEXT: Boom goes the dynamite

Woz finds Harlee in the hospitals chapel.

Again, Harlee confronts him about his involvement in Saps accident, and this time, he comes clean.

He did it for Harlee and for Cristina and for every other member of their squad.

Now, he wants Harlees help to finish the job.

He asks her to distract the guard outside Saps door, so he can end him for real.

Inconsolable, Harlee begs him to stop.

They both return to PD headquarters.

Tufo takes Woz aside and shows him Saps immunity contract.

But inside, Woz is filled with righteous fury.

Hes just been handed all the evidence he needs.

He makes a run to his storage unit and recovers the dynamite meant for Donnies security gig.

Once she learned Zepeda thought Kovach was his ticket out, Woz had Kovach killed.

All Stahl wants to know now is why.

Why does Woz need Zepeda behind bars so badly?

Leaving Stahl mid-sentence, Harlee rushes in.

Shes already put it together that Woz created the massive distraction so he could kill Sap without anyone seeing.

Woz has committed the ultimate crime at last.

Theres no turning back now.
