Spoiler: The Flashback to Jane's Family's Murders in Episode 8

Raymond Haffner is the killer. Brett Partridge slides under the bed, and Haffner says "Where'd you go?" Partridge "Hello Angela, do you know who I am? *laughs*" Haffner kills her and Jane's daughter. Brett Partridge draws a smily face. They leave the house. Haffner says "Why were you talking like Elmo???" Partridge says "I was going for creepy." "Well, you sounded high."  

After they're done they look seriously at each other. Partridge says "Tiger, tiger," then Haffner says "Grow up man."  Partridge looks sad, so Haffner sighs "Tiger, Tiger...you creep". Partridge grins, Haffner smiles back and they high 5 each other like highschool kids. 

Partridge says "Burgers at my house, Dad's away on business." They drive away to his house with some celebratory cheeseburgers. Reede Smith is first one there, already with cheeseburger and fries in each hand within a minute of their arrival, says "Comeon, guys, what took you so long." Haffner says "I took my time with this one. You know its because of Patrick Jane, Amy left me." Smith almost chokes on his mouthful of fries. McCallister appears behind him and backslaps him to health.  Partridge says "That was Patrick Jane's family??? I'm his biggest fan. You know he can speak to the dead." Bertram walks in, shaking his head, saying "You really let him come with you again?" Partridge looks offended. Michael Kirkland walks in. Haffner passes him a cheeseburger, while Reede's eyes follow it from Haffner's hand to Kirkland's mouth. 

Michael says "You really need to stop taking Brett with you." Partridge yells "I draw the smiley, damnit." Michael says "Right..." "Tell him Ray, I do a great serial killer voice." Ray nods slowly. Partridge laughs a little too loudly in Kirkland's face. Kirkland says "Did you ever make a real friend by yourself? Or does your Dad just recruit them for you?" Then the guys chorus "Oooooo" then the room goes quiet. Partridge: "Ok then Mike, lets say we have a wager, you name any one person in the world, and I guarantee I will make them to be my friend. "

Mike smiles. "Patrick Jane. I'll give you 10 years."
Brett Partridge: "Ha, that'll be easy, we've both known him since we met him in the carnival. If I can't do this, heck, you guys can kill me."

Reede: "Where's the ketchup?"
Partridge says "Here," receiving the burger with his left hand and smears some blood on with the other gloved hand.
Reede: "Awwww comeon man!"

*Lights turn on* Stiles: "Comeon Brett, you really need to stop having these meetings in the basement. No good can come of it."

As the years go on, Partridge fails miserably and his colleagues and father even try and help him to make his first friend. Partridge attracts depressed women as they sympathise with him at first, then they are endeared to him from his habit of painting smily faces on walls. But 10 years has almost expired, so Partridge is driven to his most crazy plan ever. Wait and see...
