False Facts

They never do explain why Queenie abstracted.

Kinger and Queenie who were so connected that the body program Caine created, made them a matching set.

Kinger keeps saying he feels responsible for things he did, and that he hated himself.

This makes me think that during the time that Queenie abstracted, he was pushing her away. He probably was blamed by the other programmers for them being there, especially after Scratch abstracted. Queenie obviously didn't blame Kinger, but he may have still felt so guilty he wasn't really emotionally there for her.

My best guesses as to what caused her abstraction are:

She knew she had children and felt like she'd never see her daughters again

She found out that they were brain scans and there was never going to be a way out for them

Also since they knew that touching Jax was going to allow them to see inside his mind, Kinger had to have done this same thing with Queenie and told them about it.

I'm glad Caine got his happy ending.

I'm glad he grew as a character

I'm glad the humans came to accept him.

I will NEVER be ok with the fact that he had to do all the hard work of actively deciding to be better on his own (this would be fine if it wasn't for Jax's storyline)

I will NEVER be ok with the fact he had to remove his blue A.I. brother from himself because the humans wouldn't accept him otherwise

I will NEVER be ok with the fact that no one was remotely interested in his lore, especially since it had a direct impact on their own lives

I will NEVER be ok with the fact he was actively begging for help (in his own way), including using his puppet NPC Able, to state that he feels like a prisoner in a reality that he created

The whole cast pushes so hard to help Jax, to find the good in him, to lift him up, and reach out to him regardless of what he does to them...but Caine? Zero shits given.

"But he tortured them!"

Jax caused two people he supposedly cared about to kill themselves

"He's not human so he doesn't matter."
