If Elio was any type of drunk, which is impossible in his case because he doesn't drink like that on top of having a ridiculously high alcohol tolerance - a shared Argentium trait, he'd be a combination of a <Happy Drunk> and an <Affectionate Drunk>, matching his generally benevolent nature.

In short, Elio's personality wouldn't change when he's wasted, but he's prone to be more open, expressive, and honest about himself and those around him - albeit doing so in a respectful manner (which is impressive since drunk people are prone to be unrestrained via certain cranial functions being extensively repressed in an intoxicated state), while acting more brotherly than humanly-thought possible.
