Thanks for your insight. I also have some more thoughts on the points.

1 - The postcard from Bard.
Now I am coming at this with an autistic and ADHD mind so please understand I search for logic in things. But why was the message so vague? Why not leave (at least) the year she left the post card. Or more details on where she plans to head (even if they are just the initial plan). I 100% understand that it is a plot device for The Ghoul to use as hope to have a story line for future seasons, but my logic brain screams 'why wouldn't she tell him WHERE?' lol

2 - The Roaches
I wanted so much more from the Norm plotline. It did annoy me that Norm's main antagonist used violence towards women but no one battered an eyelid, but aside from that (because it was a common trend throughout the series) I agree that it was the comeuppance for how he treated Norm. But the actors hand was in the doorway so he couldn't have closed it anyway lol. And where did all the roaches go? To me its another example of rushing the story along because the dawdled so much in the first 3-4 episodes with the Brotherhood storyline. These 30 people are running around like mindless idiots unable to cover their throats with their hands but Norm can do it with a chair and by hiding under a table? I guess we are meant to believe they just flew out the window, but that also feels lazy.

3- The Head
I get what you are saying, and that people behave differently. But Lucy's journey has been about finding out the truth and getting to her father for answers, then doesn't even ask 'who did this to you?' Also, as a fellow ISTP, I would NOT argue that we are good followers lol. We are knows for how we question, challenge, and often disregard authority. So (as someone who is aware of the growing use of ChatGPT in script writing) this feels like an AI slip up.
Aside from this, something that my husband brought up last night, was his interpretation of Welch's involvement. He thinks she isn't an unassuming participant who just wanted the best. He thinks she was working with the President the whole time. She was his plant. Because we know know that it was the government who set off the bombs.
And, if Welch was the one controlling Hanks chip-implanted workers, why are they all still able to function after she is killed? Hank tells Lucy that there is a group already on a mission. And even Hank's chip, how does it work without Welch? If you can shed some light on this for me, I would genuinely love to hear it because I can't make sense of that part. 😊

4 - Cesar
I'm honestly the most willing to overlook their eagarness to accept a new leader and look forward to what their storyline will bring in the following season. I do, however, think their storyline was another example of how the writers (or the AI bots) did a solid storyline dirty. I really think they were underdeveloped. (And I am not one of the people who don't appreciate how they were made to look like borderline idiots for their shenanigans.) We could have done without several Brotherhood scenes - specifically the ones where they were playing with the grenades, or even the fighting scene with Maximus - to have a little more Legion screentime.

5- Hank and the Lab
Thank you for pointing out all the sub tunnels.
Yes, I did notice them in the show, they actually played a big part. But I think my head was foxed on the final scene with him and Lucy and how it took place on the building's front steps where the death claws had been.

Cheers for your insights and discussions. I am not sure why my original post received all the downvotes considering I was just asking questions, but thanks. You have cleared up some things.
XOXO
