Retribution

I think Scott Wentworth was busy in Stratford during the filming of this episode.

The actor who played Cooper, shows up in fourth season as the Colonel of the military academy in Special Forces.

Chris really hurt himself on the coffee table. He cursed and that line had to be dubbed over.
 Monica Sztybel
Chris also hits his head against the Stealth a short time later as he gets in it.
 Monica Sztybel
At one point during the last fight, Chris is not wearing his gloves - oops.

Robert Lansing was ill with cancer during his work on KFTLC. This episode was not supposed to be his last, but a good way to explain the actor’s need to be away for treatments. Unfortunately, he died a few months later. This episode has turned into the best send-off for a very talented actor.
 Monica Sztybel
Although filmed second to last, this episode aired last. I believe Michael Sloan wanted it that way.

Script differences  
In the tease of the script I have, it starts out with Blaisdell as a nervous wreck, having trouble with cufflinks. Annie fastens them with ease. They're in the kitchen.
 Monica Sztybel
Then Peter goes through his nervous routine with an added line in the beginning, "Is this the good crystal?"
 Monica Sztybel
After Paul's outburst in the precinct, there is an added dialog between Skalany, Jody and Borderick. There is no mention of Peter leaving after the scene, so he must be sitting at his desk as they're whispering.

Jody: (softly) "What the hell was all that about?"
Skalany: (also soft) "I know the Captain's rattled by what happened last night, but..."
Jody: "How could he talk that way to his own son?"
Broderick: (as he passes) "It's not his real son..."

In the scene between Blaisdell and Blake, after Paul tells him that the knowledge of the bug has to stay between them, Blake asks, "Shouldn't you let Peter know about this?"
Paul: "No."
 Monica Sztybel
Instead of "What troubles you, Son?" Caine repeats Peter's line, which is, "Tell me what troubles you?"

The flashback starts with a few more lines before what we see in the episode.

DESCRIPTION: "In the courtyard. Peter runs into the shot. He looks out at the greenery beyond, his hands clenching into fists. Tears spill down his cheeks. Caine appears behind him.
Caine: (gently) "Tell me what troubles you."
Peter: "It has nothing to do with you. Just leave me alone."
Caine: "You did not go to your secret place. I took that to mean you wanted counsel. I will do as you ask."
He begins to move away. Peter turns.

The scene goes on from there.
 Monica Sztybel
The script lists the bar the cops hang out as Chandlers, but we know it's different:-)

There is more dialog between Kelly and Peter before Stiles shows up.

She's handling him with kid gloves.
Kelly: "You don't think the attack has to do with police work?"
Peter: (shaking his head) "Something Paul... excuse me, Captain Blaisdell... said about the past. A 'Falcon's Wing' darkening over him."
Kelly: "What does that mean?"
Peter: "Who the hell knows? He's always so secretive." (glancing past the camera) "Oh, great! This is just what I need!"

Captain Stiles walks in.

Kelly: "Who's that?"
Peter: "Captain Bartlett Stiles, head of the SWAT team. Gives the term 'martinet' a whole new meaning."

When Peter comments that he didn't know that Stiles and Blaisdell go way back, Stile says, "What you don't know about me would fill a grave." Scarey thought.

When Peter asks him what Kiev has to do with Paul today, Stiles says, "The past reaching out like a cold hand on your shoulder. Sounds like something your father would say."

When Peter comments that he didn't think Stiles like Blaisdell, Stiles says, "I don't like anyone. Haven't you heard the talk around the precinct?"
 Monica Sztybel
The scene where Blaisdell shows up at Caine's place is set up differently.

DESCRIPTION: "Caine has his back to us. Scuff of sound behind him. He whirls into a fighting stance. Blaisdell moves into frame. He's dressed exactly as we've just seen him, same coat, same clothes beneath. He's dishevelled, out of breath and there's blood on his coat and hands. he looks down, startled. Camera pulls back to show the bodiesof the would-be assassins lying unconscious on the floor."
Caine: "They came to kill me. Are your enemies my enemies?"
Paul: "Could be. If they believed you would help me." (Caine looks at Blaisdell's bloodied hands)..."

The dialog is the same from there, but there's no instance where Paul cleans his hands.
 Monica Sztybel
Instead, Paul apparently has washed his hands at home. Annie discovers him packing in the living room, but there's some added dialog.

Paul: "It is dangerous for me to stay here."
Annie: "You mean it's dangerous for us. For Kelly and myself."
Paul: "That's right."
He makes a move past her. She grips his hands.
Annie: "The towel in the bathroom had dried blood on it. I could smell it. What happened, Paul? Why are you so frightened?"
Paul: "You remember John Matheison?"
Annie: "The Senator with the stuffy wife? You hate him."
Paul: "Not enough to kill him. But that's the way it's going to look..."

Then he goes on to tell her not to tell Peter he was here.
 Monica Sztybel
After Peter's altercation with Caine at the Ancient's apartment, he leaves and Lo Si says, "He is in great pain."
Caine: "Because a man he loves and respects is in greater pain."
 Monica Sztybel
Paul and Stiles discuss the diary. Stiles asked Paul if he went back to look for it. Paul said he did the next day. Then Paul wonders if that's when Caine took it. Stiles is confused.

Stiles: What the hell are you talking about?"
Paul: (softer) "Attempting the impossible."
 Monica Sztybel
Paul gives chase when the cops arrive. He runs until he's trapped and that's when Peter walks up and reads him his rights.
 Monica Sztybel
There is a scene where Caine sits and tries to recall what he saw in the diary after he has returned from his journey. He then opens his eyes and says, "Yes."
 Monica Sztybel
In the interrogation room, Paul explains that the reason the killer was dressed like him was because his office is bugged and he was on the phone with Annie, telling her what he'd be wearing.

During the conversation between Cooper and Strenlich, Paul looks at the mirror from the interrogation room and says, "Tell Detective Caine to take a break, Strenlich. He's getting tired."
 Monica Sztybel
They have a scene where they show Stiles entering Caine's place, gun
drawn. Caine tells him he doesn't need it.

Stiles: "You said you had some information for me? A matter of life and death?"
Caine: "A matter of survival. Blaisdell's survival."
Peter enters the room in time to hear this.
Peter: (to Caine) "Got here as soon as Blake gave me your message." (looking at Stiles) "What's going on?"
 Monica Sztybel
At the warehouse, while Stiles, Cooper and Caine are talking, the script describes Peter as, "groggy, blood down one side of his head..."

When Peter pulls Paul off Stiles, the script description is: "Blaisdell leans against Peter, then hugs him close. Caine moves into frame and takes Peter's arm, making the triumverate complete..."
 Monica Sztybel
After Blaisdell hugs Peter in the tag and walks off, Caine says, "Great love appears indifferent. Great wisdom appears childish. When he has embraced his loneliness. When the demons are gone. He will come back."

And then the scene ends the way it did in the episode.
