Chokim, AKA known as the greatest love scene ever.

Cho walks in the scene from behind the office corner, about 20 feet away from, at the moment, arguing Abbott and Kim. As Cho walks toward them, his motion slows down and the camera intermittently switches back and forth between him and Kim's sensual attention completely devoted to evaluating of Cho's figure from head to toe. Her lust is more dripping than the pen she unconsciously brought to her luscious lips. 

Kim's day dreaming is abruptly interrupted by Abbot's annoyed exclamation;
"Agent Fisher... was I clear enough?"

To what she replies:
"Sorry boss, can we discuss this later?"

Abbott shakes his head and walks away, meanwhile Cho reaches Kim and she adopts his speed of walk right beside him. Cho doesn't seems to notice her.
Fisher's question is direct and without beating around the bush:
"Cho... Wanna have sex?"

Cho gives her a quick glance and replies:
"Sure." while the second part of his answer comes as he turns his head straight ahead, again: "Why not?"

They continue to walk silently by each others side throughout the next two hallways when suddenly the hallway ends with a wall infront of them. It also branches to the left and right. The arrow pointing to the right reads: the interrogation room. Kim turns that way.

Cho turns left.

For few seconds the hallway is empty... then Kim runs back from right wing to catch up with Agent Cho. Finally, she's caught up with him when Cho sits down to his desk and starts flipping through the file in front of him. Kim halts at the desk. Irritated she utters: "So?"


Cho looks up to her with his trademark expressionless and comes to riveting conclusion;
"Oh, you mean right now!"

Her WTF countenance is more than enough to send the suggestive message even Agent Cho can't misinterpret. He stands up, gently touches Kim's elbow and invites her in the nearby direction:
"Let's do it."

They walk few feet further and Cho inquires:
"Would you mind?"

Jane looks up from his couch. Smiles, and vigorously jumps away, but hastily turns back and with playful tip-toe goes behind his beloved furniture, pulls a plastic wrap over the seat and implies:
"Go ahead, kids." then with grin on his face, for the last time before he leaves the scene gives the voice to every true fans expectations:
"It was about time."

Cho, in modestly uncomfortable manner but decisively firm decision wraps the love scene up:
"I'm on top."

So i read in the comments of a youtube video  "enough time for them to get married though! ;) " refering to jisbon in season 7 , because of the only 13 episodes. And i tought, enough time for redjohn to comeback, kill the entire team (new and old ) , kidnap lisbon, then patrick and red john finally meet (for real this time ) after an epic mindgame between them, red john says "Well patrick, now is indeed game over , and i won " ( he kill himself so patrick wouldnt have his revenge and avoid to tell him where lisbon is ) . Jane approaches slowly to red john , takes his gun , then he sits in a chair just like in season 3 finale , drinks some tea and slowly aim the gun to his own head, he says " At least i hope van pelt was right , and u girls are in the other world so i could see you now "  then the camera slowly goest to the right showing some trees , and then "BOOM !!! " 
SORRY FOR BAD ENGLISH.

The whole thing started spiralling out of control with the introduction of the BA.  I know that "Tiger Tiger" was there for years, but It could have been nothing more than the fact that RJ's mom read him Blake poetry as a kid after repeatedly dropping him on his head.  Then it was a compulsive thing RJ passed on to his followers.  Before Season 6 I thought of them saying TT as a way of giving PJ a big FU when he thought he was going to get useful info out of someone.  The fact of having a psycho serial killer with a cult like following being the same person that leads a very secretive society of law enforcement offers, not only is unrealistic, but also made it impossible for everything to work together.

Now that everything got convoluted into a giant pile of donkey dung, the only way to salvage the first 5 seasons is to back track a little and separate RJ and the BA.  Let McAllister be the leader of the BA.  Maybe RJ even had a friend inside the BA that helped him out from time to time.  Yes they used TT as a calling card, but that is the only definite link between RJ and BA and could have been RJ's way of selling out the BA, or maybe RJ was actually part of the BA at one point, and got obsessed with the TT thing.  But i would see him as a maybe a member but not the leader.  even if it has to be McAllister, letting him be a creepy local sherriff who moonlights by hacking up girls makes sense, but not the leader of BA.  (On a side note, the biggest error in heller choosing mcallister is the way mcallister was in the beginning.  He couldn't even control his chub long enough to take down GVP, but we are expected to believe that he took down all those other women over the years without screwing up). 

The hot chick from Leverage never said it was RJ that hired and killed her, just that he had the ... tattoo, which was an indication of BA, not RJ.

And no, i don't think it was CHO.  I just picked him to honor the fact that he is the best thing going for the show now that JISBON is intact.
