I headcanon that Jayce Talis is very smart, but also very stupid - specifically when it comes to things most wouldn't consider 'normal'. Dude is definitely one of those motherfuckers that lives a large portion of his life thinking oranges are spicy before being informed (probably by Viktor) that citrus shouldn't actually make your mouth itch and that he, in fact, is allergic.
This also extends to another headcanon of mine that Jayce has mild tinnitus. Not to the point of being noticeable *all* the time, but if it's quiet enough, he hears a ringing. Silence has never been 'silent' for him before.
It would come up probably when Viktor questions why Jayce always has something going that makes noise. A fan, maybe, or just Jayce generally humming under his breath when a conversation lapse.
And then, in all his dumbass glory, Jayce looks him in the eyes and goes "Because it's loud?"
Upon being questioned, he'll explain in more detail that it doesn't have to be *entirely* silent to hear a faint ringing, but he doesn't get why everyone else can just tolerate it. Viktor then has to inform him that all the 'I don't need hearing protection' Jayce spouts in the lab is probably the cause of this.
Or the fact that Jayce has probably taken more than a few explosions to the face. Either way, boy's kinda stupid.
