That's why Martin stayed out of the conversation all that time, why Martin didn't act until I got a response and kept asking.
He didn't intervene until Mithias dropped unconscious.

And what he did was just a simple transfer of data. At least I explain how it works, instead of mysteriously going "And suddenly my character could do X and no one could explain how.". That's actually quite limiting, because now I don't know the awnser OOC, but Martin would IC. And I have to go and think up reasons why Martin doesn't take a look under the hood.

So yes, he is more powerful than the flying warship, but mostly because he took precautions against the thing a long damn time ago.
It's been established a long time ago Martin could read and write in someone's head, and we've always treated AI to work similar enough for it to practically the same.
This was the end of the previous chapter remember?

But I'm keeping Martin in check. And he never threatened anyone's life. As opposed to almost every other character in the story.
And Stein kept talking about how he had a plan to kill him and his brothers. How was Martin supposed to act?
The constant insults and underestimating Martin can handle, and the threats at his life Martin can scoff at. But how was he supposed to act when his brother is being tortured and sends a dying farewell to him?
