Red needs to let go of Liz. End of story.

She is the ultimate betrayer, and there is no excuse for any of her actions on The Blacklist Season 7 Episode 10.

Warning. If you haven't seen the episode, don't read any further. Spoilers ahead. 

Liz's stupidity is getting old -- as is her ridiculousness with changing sides.

She doesn't understand what loyalty is or that it is the most important thing to Red.

If anything, the woman needs some serious mental help.

Just because she formed a relationship with fake Katarina's alter ego, Maddie, doesn't mean that she should have trusted her the way she did or believed everything fake Katarina said to her.

And for her to go to Dom and ream him while he's in a coma was the lowest thing she could do. 

She can be mad at him, but to shove both Red and Dom away and dismiss everything they've said to side with fake Katarina was a stupid mistake.

Red cannot forgive her after this betrayal. 

It doesn't matter what his promises were. It doesn't matter how much he loves her.

Sending him to jail is one thing. Siding with this woman is another.

If it turns out that Katarina is indeed a faker and Liz comes to realization she's been duped again, there can be no sympathy for her.

He doesn't need to kill her. He needs to walk away.

Despite everything Katarina said and all her "evidence", she's a liar.

Her sob story about why she lied about her identity when she moved next door to Liz -- to want to get to know her and Agnes better -- is not to be believed.

The fact that she was torturing a man who was very close to Red -- and it doesn't matter if he was the real Ilya or not -- should have been enough to convince Liz that something was seriously wrong with this picture.

Whatever the big secret is, all of them from Dom to Red to Ilya, have gone to extraordinary lengths to keep it a secret. And it's clear they did it to protect Liz. 

Ilya almost lost his life trying to keep the secret. Dom is barely alive trying to keep the secret.

Red has gone above and beyond to keep the secret.

Why? To protect Liz.

So, it has to be one helluva secret that everyone wants and needs to keep it wrapped up so tight.

However, Dembe wanted Red to reveal the secret -- as did Mr. Kaplan and Liz's adoptive father (I can't remember his name.)

It cost Kaplan the adoptive dad their lives and almost cost Dembe his relationship with Red.

And my thinking on that is perhaps neither of them knows the whole truth. 

Losing Liz will be heartbreaking for Red, but he's got a new buddy with Ressler. 

And Harold is always on his side. Aram will probably join the club too, and as much as I don't like Park, she might become Red's new best friend as well.

One thing that's for certain is that any potential romance that might have happened between Ressler and Liz will be dead and buried when he learns she helped Katarina escape.

Ressler is a bad boy.

And the fact that Red left the Dream Weaver guy for Ressler to take care of shows how dark our favorite FBI cowboy has become.

The only hope for Liz is that she's doing another one of her rogue missions and is faking it all to see what she can find out.

But the idea of her using her brain for something as complex as manipulating Katarina is laughable.

Katarina's trick was a good one, but there were problems with how it went down.

Specifically, she had to know that Red was there watching. She also had to know that Red would follow her.

They also had to time it right for Red to see Katarina get gunned down the way she did.

There are a lot of threads there that needed to be laid out perfectly.

Still, it was a good ruse, but I have to wonder if maybe Red thinks it was a ruse.

He's not stupid.

Then again, as smart and connected as he is, he hasn't been able to find Katarina for the entire first half of the season.

He had to have felt at least a little stupid that Katarina was right under his nose and he didn't know it.

He should also question why Liz never mentioned her neighbor.

But those are details (maybe even nitpiks) that won't be answered.

Harold calling out Liz for her lies was the greatest thing, especially his reminding her of why they need their allegiance with Red.

He knows she's lost focus. 

If he was smart, he'd see that all this drama is too much for her, and she needs to get shelved.

Again, sending Red to jail, faking her death, the continuous lies and deception should show them all that she should never be trusted again.

It won't happen, but everyone, including Park, needs to give her the side-eye from this point forward.

What wasn't answered was Park's big secret.

It had seemed that maybe there was a connection between Katarina's minion and Park when she knew who he was in the car. 

I might have missed him telling her his name when she was questioning him earlier, but there has to be a connection between Park and Red or Park and Katarina.

Otherwise, why bring it up at all?

It was also good to see that Arama's crazy antics with his married lover turned into something useful and wasn't a complete waste of time.

What's also maddening about Liz's actions (and maybe even The Blacklist in general) is how she always has to side with someone else.

On The Blacklist Season 6, she sided with the sister -- someone she didn't even know. Now, with a few choice words, it's Katarina.

I still enjoy the days when Liz and Red were working together as a team back at the beginning of The Blacklist Season 5.

The continuing twists and turns are exciting, but also frustrating.

And Liz's inability to stay on Red's side is frustrating as well. Plus, let's not forget that the biggest mystery is and has been about the true identity of Red.

I know that I'm not the only one (the entire fandom perhaps) doesn't care anymore who Raymond Reddington really is. 

And that is probably the most frustrating of everything.

It was an exciting fall finale, and now we have to wait until March to see what happens. It's going to be a long winter!

Two final notes: Red kicking Park out of the car? Classic! I loved it! And the other great Red moment was in the Chinese place when he told the receptionist he had two guns for two appointments. 

Red has a way with words!

One final, final thing. When Red told Liz about Katarina, it was telling that he called her "the woman" and tossed it off as if it was nothing. He didn't discuss it with her or try to comfort her.

Red knew Liz knew it was Katarina so that's something to keep in mind!

Over to you!

Is Liz playing her own games with Katarina? Or has she turned against Red again?

How should Red deal with Liz's newest betrayal?

How should the rest of the team deal with it?

What do you think about Liz's rant to Dom?
