for as long as you remember, John has always been dead start sure, he has a few mess ups hearing dare like occasionally like mess with demons and other stuff, including with spells, but you, you had nothing, he has magic you don't. In fact, both of you living completely different lives, while he's out there being a complete menace in the magical society.
You just well stayed, you sure you so things like one are 2 things are to even sell couple of trinkets, but it really doesn't matter cause you're always looked down upon just because you are Johns twin brother than nobody, the failure, the black sheep...
You just got used to it until one night you're just walking down the same God damn street. That's until you almost got attacked by some demon, and John coincidentally managed to save your ass, and this is the first time you guys have seen each other in years. So yeah, it's a little awkward, to say the least...
