“Old Wounds” is co-written by Brian Dietzen, a.k.a.

Or is it Hurricane Parker?

It’s definitely not pretty, but lancing that old wound turns out to be darn necessary.

Then a gunshot sounds and we head into the credits.

He hasn’t resurfaced by the next morning, so the team starts working through what they know.

Parker shouts at her too.

So Brighton explains that the firefight with Wills' drug-running crew is what put him in the chair.

Parker’s convinced that WillsTech is a drug front, but Brighton’s reserving judgment.

(He also invites a starstruck McGee and his family over for dinner.)

Then Brighton offers a clue to the mystery of Alden: Parker didn’t always have a million hobbies.

That old Parker surfaces during the interrogation of Wills, though.

Parker says he’ll read it after he takes out Wills, which alarms Brighton.

In the backseat, they find a big bag of the W-branded pills.

They have the evidence they need.

Now they have to find Parker.

Parker has indeed snuck out to confront Wills on his own.

Wills pleads for his life, calling himself trash, not even worth killing.

But McGee repeats Wills' question, asking why Parker was there alone.

He assures McGee, “It’s over now.

I’m good.”

But he doesn’t sound good.

Also, with Parker benched, McGee’s in charge of the after-action report.

In the morgue, Palmer cleans up Parker’s forehead gash and graciously accepts his apology.

“No one should be judged by the worst days,” says angel-on-earth Jimmy Palmer.

Then he and Kasie head home, leaving Parker with Brighton.

His friend tells Parker that he’s stuck, and arresting Wills won’t help.

Brighton dealt with that night, the shooting.

And the solution is to finally read that letter.

When Parker refuses, Brighton opens it and reads it himself.

Parker can’t take it and grabs the letter to read it himself: “That was yesterday.

Today I’m choosing to move forward.”

The letter urges Parker to accept help for the fear and trauma that have him in their grip.

Here we cut to McGee bringing coffee to Torres and Knight, still at work on the report.

“You have a partner,” Parker reads from Brighton’s letter.

Another cut, this time to Kasie and Palmer fist bumping to their good work as they leave.

“You always have a partner in me,” Parker reads.

“So first know this: I forgive you.”

Say it to yourself: I forgive you."

The letter asks Parker to read it every day until he can accept that.
