I've never seen any headcanons for him (for some reason), so...
Steinbeck doesn't like being called by a dimunitive
Like
He's talking to Mark and he's like: "yep it was kinda fun, right, Johhny?))))"
And at that moment Steinbeck looks at Mark with such a look as if he ate his grapes and like: "don't call me Johnny.."
And after that Mark calls him that just to piss him off
