Well, could he have done something wrong? Of course he could. I don't know what he does for them, but why not? He could easily have screwed up and done something that would have angered Error. Or, Error could simply see from other people's examples what it means to anger Dream.

At the same time, in every comic by this artist, Dream was quite cruel, enough to say that it is not worth attracting his attention. When speaking of "brothers," why can't it be a figurative expression? Like he was sold with other puppies as servants and he called them/they were his brothers?

Dream tends to take responsibility where it is not only not required, but he is not even asked for help. He could very well be a responsible owner of an estate, with slaves like Blue, and be so busy that he was rarely home and traveling on business.

I actually think Dream is the master. It's just because Ink is too flighty and irresponsible by temperament. He doesn't take responsibility for what happens in the AU, even if he doesn't like the events taking place there, because "history must go this way and no other way."

Why does it have to be Ink?
