sorry for the shitty tl;dr!! but june is a colorado native, having moved to aurora at a very young age and only recently left the area for the first time to attend ucla for environmental engineering and film studies. (technically he's only registered for the former, but petitioning for a double major are in his plans.) as you can probably guess, he's hugely into a lot of environmentally focused things like urban farming, adhering to seasonal buying, and so on and so forth. he tries not to be annoying about it with everyone else around him but don't be surprised if he just suddenly starts taking your garbage from you and sorting it on his own. he's incredibly close to his dad (male versions of lorelai and rory basically) and adores his paternal grandparents, who also had a hand in raising him, which basically just means that he not only loves bragging about his family but also that sometimes he gives off serious bedelia vibes. june is a great hype man, always ready to get people excited about anything and everything, loves supporting everyone's dreams, and is prone to being the unwanted dad friend. he will take care of you. except he's also mad stupid petty and isn't afraid to get childish if he feels wronged, which may lead to him offering to cook breakfast just to serve up burnt toast.
more to the point though, they could definitely have long conversations about photography, music, or whatever else either of them are feeling that moment because if jude is a chatterbox june will be happy to indulge! also their names match, it's perfect, obvs this means june will constantly suggest they should open their own business together.
