[SPOILERS] Inside the Episode 804 - The Last of the Starks (Behind the scenes)

Warning: SPOILERS, obviously. Please keep comments relevant, ie, no spoilers outside of this specific episode of the "Inside the Episode" series, no production leaks, etc.
Watching this, it looks like A.Ron and Jim were incorrect in their analysis of Jamie in the instant talk. Apparently he has gone back to Cersei, to not kill her but to be with her.
There's also confirmation that Missandei's "Dracarys" was an intentional message to Dany to burn all of King's Landing down.
With the first point I feel that D&D have essentially betrayed Jamie's character. It would be one thing if he were leaving Winterfell with the intent to kill Cersei and finding himself unable to, but here we have him leaving with the intent to be by her side. It just seems to me like a huge betrayal of 7 and a half seasons worth of character development and doesn't make any sense to me at all. But I digress.
The second point makes sense, people have treated Missandei like complete shit since she got to the North, and further King's Landing, and then she is taken prisoner. It is understandable that she'd want to see what she perceives as a carnival of hatred to burn, and to be avenged.
What do you think of this Inside the Episode?

Comments
Jaime already knew that the army was going to fight her when he stayed behing with Brienne. The thing that changed was hearing what she did to the dragon and Missandei. He sees how far she is willing to take this,and seeing that surrendering is no linger an option for her.
Jaime knows that he cant be with her now. Heck, Jaime knows that even going down there means she might execute him on the spot.
That being said, I hope that this time is different
In their own words:
That directly implies he is not going back to kill Cersei but to be with her as lovers once more. You may say that D&D can't explicitly say that he is going back to kill his sister, but that would be pretty inconsistent as they explicitly state other plot points such as with Jon, Dany, Tyrion, Missandei, and Cersei.
Here's an example with this quote Re: Dany's and Missandei's motivation:
So, D&D explicitly state everyone's motivation. In the highlighted it confirms that Missandei's motivation is specifically to see King's Landing burn. I do not think that it tracks that they'd (D&D) be ambiguous with Jamie's motivations and clear with everyone else. I think it's pretty conclusive that for now Jamie's motivation is to not go back to kill Cersei, but to be with her again.
Once again, I'll post this quote:
Contained within is also confirmation of how Jamie feels about Brienne, he loves her.
I agree that it's it's incredibly stupid and it massively betrays Jamie's characters arc but I don't see how you can refute the information as given. I don't want Jamie to be with Cersei but I think at some point you have to take D&D at their word.
If Jamie kills Cersei it makes what they put on screen pretty ridiculous. There's no reason to keep this information from Brienne if he truly loves her. She would understand, I think.
I find it odd that Arya doesn't intend to return to Winterfell. They made a point of her saying that on her way to join Sandor. Makes me wonder what her long-term plan is if she succeeds in killing Cersei.
-Jaime knows that Cersei wants him dead. She paid his sellsword friend in gold and castles to assassinate him, if it wasn't apparent enough.
-Based on show logic, Jaime likely has been told off-screen about Cersei and Euron's relationship furthering for political reasons, if he didn't already assume that was the case.
-D&D has stated in post-episode interviews that they intentionally did things just so that you would not see a big twist coming. If they said that Jaime was going with the intention to "stop" Cersei, every fan page would have posts about how Jaime is going to kill Cersei.
Jaime may be obsessed with his sister, but I think most people would characterize him as a realist even in regards to Cersei at this point. He knows that even if she allows Jaime to live, they can't be together now. Jaime only left to go to her after he found out how crazy and reckless she is being. He knows that there is no way out of this alive for Cersei now, unless, I don't know, he gets her to escape in the middle of the night. I'm sure he realizes that she won't try to escape, but it's his sister, so he has to try. More importantly, he likely knows that she won't go down without taking out a lot of innocent human lives with her, so he's trying to stop her from that as well.
I don't think that he is going down there explicitly to kill Cersei, but just to see if he can talk any sense into her (which will likely end with 1 or both of them being killed).
It'll probably be the culminating scene of tomorrow's episode, because it won't hold as much weight in the finale.
For those of you that think Jaime is just going down there to kill her. Do you really think he has the thought process and ability to kill the woman that he believes is carrying his child. You saw how he reacted after Myrcella died and how happy he was finally being able to express emotions as a father.
i just couldn't see a scenario where they explicitly state all characters motives, honestly, with the exception of Jamie. i get that we all (most of us) agree that he should have went back to do what we wanted completely, unfortunately that didn't happen. Gotta subvert those expectations. (except they weren't subverted cuz they basically told us what was gonna happen. lol)
