I made a few changes to these pages instead of moving on. Mainly I wanted to add in the glowing arm which would be visible to Insight. Adding it in the same page where his arm should be visible in one panel versus the other shows would further underline that Insight's new vision is fluctuating and not yet under her control.
As for what's going on with the arm, the Prisoner's bones in his left arm has been carved into like a magical item. Basically his left arm functions like a staff or a wand, which in Wardenverse - acts as a focusing lens for magic. Which means his magic can be focused into razor thin strands of force. The trade off is that he is unable to add in other elements other than a framework of pure solidified mana often used to create shields.
