Joseph can read (sort of) but he’s dyslexic, I don’t think people understood anything about it in these kind of times though so there wouldn’t be a word for it. I put in that [i]maybe[/i] he made a passing comment about it to Elissa when they were younger, and he’s never said anything to anyone ever since, as it sounds like a crazy thing to explain, in that particular time. So, it’s up to you if you want Elissa to recognise it, it could be both a little unsettling yet somehow reassuring for him that she knows what he described to her, a long time ago.
