Oh. The instant those markings come out, his spider senses start yelling at him. His sense of color is strange anyway, courtesy of magic-induced tritanopia, but when he's staring at something magical? It's a million times worse. He actually winces just a little as the markings seem to dance in front of his eyes. (He really needs to find himself a set of goggles soon or he's going to have a lot of trouble at this school.)

"What - what am I looking at?" Obviously something's up, but he can't tell what his senses are telling him. Gingerly, he reaches to touch Héctor's hand? As if doing that will help. "Is that a rune thing or something?"
