While I have been disappointed with the show post-Red John, its not because McAllister was Red John. If we had gotten more answers I would be fine with it. I'm also a fan of strong villains but the show was clear they weren't going that direction. 

As to the last episode being called "Red..." something, I think more likely the hidden title is "White." As in "White Wedding" between Jane and Lisbon. If by some chance the show does get renewed (someone can correct me if it has been officially cancelled), they have a lot of paths to follow after that.  

"Mr/Mrs. ................... I apologize for that,.. Jane!?" - the sentence that used to accompany every single episode...
G00d old times <3

they are the strongest people in the universe, they don't even need to see a shrink !
what's wrong with them ?
Haffner dies, they'll cry an other day
Ardiles dies, they don't cry, they prefer to get a warrant to search in a gloomy warehouse at night, I can't even see the point of that.
La Roche dies, whatever happens to his dog, we didn't learn what they could have find in that warehouse, like goldfish they forgot why they came there in a first place.

A hooded hooked nose white man with clean neck skin and a left handed triggered shotgun almost killed a baby and her left handed pistol mother and All they say is : "Good to see you guys" and guess what, a black man is beyond the twelve suspects ! are you freaking kidding me ?

Even if it happened really fast(and was obviously a stuntman not the real suspect), why they didn't try hypnosis or a remembrance technique to get more informations. You can pause at 02:04 to get a good snapshot at him.

How will they act in the next episode ?
How the suspect knew about the new location of the team ? bugged phone again really ?
Does the suspect really want revenge from everyone, or does he really know which one he has to kill ?
Haibach has a wrinkled neck.
And what the hell with John Hutten ?  It said at the end that he was just usually secretly cheating on her wife, why did he let the "screw you sticky note" !

It's like they just throw some candy to keep us on waiting.

Lisbon, She's the one ! No just kidding

Seriously what's up with these people ?
To whom died and were supposed to be their friend ...
Why Lisbon and the team aren't showing any kind of mourning.
Or even showing some interest about what's going on.
They are all psychopaths.
First, Ray Haffner, then Ardilles, now Laroche.

We can't come up with any real theory now, this is just nonsense.

Why do we still hope for a future explanation xD

She is the one he seems to trust implicitly. However, I think he is keeping her close to keep an eye on her.

Assuming all of BH's clues are credible and will be explained at one point............. i would like to point out something interesting. Back in the season finale of 2nd season,before Patrick enters that empty building, he makes a phone call to Lisbon telling her his location and that he will wait for her to arrive. However,he does wait a bit and then grows impatient ,then enters the building alone. My question is how did RJ track down those 2 psycho copy-cats? And better yet the only person who knew Patrick's location at that time was Lisbon......................... It could be Red John keeps tabs on Patrick's calls but that doesn't mean he's sitting around 24/7 eavesdropping on his phone calls? Red John is very careful and he knew nobody else was going to be there so he went there himself to confront Patrick and kill those 2. Any theory on how RJ knew the location is welcome.............

He is Marcus Pike. He is a high up in the fbi. He will be more than just Lisbon's love interest.
He kinda looks like the hypnotist from the russet potatoes episode right ? Like looks just like him.
Jane knew red john was in the fbi.
Thats why he said to Lisbon, "its like a fishbowl but its US looking at them ".

Side not about janes house NOBODY has said yet...
-Why can jane Not recall what happened before the explosion?
His flashback memory is from right before the gunshot .
THIS IS PROOF THAT A HYPNOTIST WAS PRESENT !!!
How else could janes memory not contain the gunshot ?
Also why did jane turn up the heat ? Lol

He is mar..he is marcus pike !
