Oh, I see. They are covered up by the speech balloons or out of shot. It really makes Sulla look like a normal little kid versus a robot child.

Your efforts are appreciated, that is very respectful of you

Edit: I misunderstood your comment.

Kid Sulla has the red skin lines on page 26 of this same chapter. But Sulla’s skin lines are on the chest and the elbows (and maybe the knees), not the hands. Brendan places bandages on top of those lines, presumably because the skin creation and grafting process is still experimental and he doesn’t know how it’ll react to long-term usage.

So at this very early stage, they seem to be used mostly on joints.

(Apologies, I’m trying to use gender neutral pronouns to refer to Sulla. This is difficult for someone like myself, who speaks a language where they’re almost rarely used…)
