Makes me wonder if the comics really are canon now. I admit something like this is actually quite dark especially the context in which the injury was received. This to me is one of the times where the comic and the show diverge. I’m pretty sure Inkwell will never appear or even be mentioned in the show and that this story and indeed most of the events and characters from the comic will remain exclusive to the comic as it seems to be almost an alternate universe; the comic writers seem the do their own thing and only loosely relate the comic to the show. In short, I don’t consider this canon, but rather a stand alone story; official fanfiction if you will.
