Oohhh I'm very excited for that one! Just came up with it over the weekend, so it's still all shiny ;)
Crossing my fingers this doesn't actually happen, but I thought... what would happen if at the end of season 3 everyone in the Batch died but Hunter? What would that do to him?
The answer: A lot of bad things.
Hunter is broken. Barely functional and catatonic. Rex doesn't know what to do. He knows he can't let him go off on his own, not in the state he's in. He feels responsible how the way things went, and he owes it to them to make sure Hunter's okay.
He's not. After two days of this, Hunter just... disappears. No word or message left behind, he takes one of the ships and vanishes. And Rex isn't sure he'll ever see him again, not alive.
For a standard year, Hunter wanders the galaxy, aimless, taking what jobs he can, leaning towards the violent, dangerous ones. He excels at hunting, and he would be a class one bounty hunter if he wouldn't piss of the Guild at every turn. He doesn't work well with others, and he doesn't much care for rules.
He's mean, ruthless, and most of all, hollow. He's little more than an animal, moving from one need to the next, not staying anywhere too long. He sees others as an obstacle or a means, depending on how cooperative they are. He barely talks, no more than is necessary, and he rarely sleeps more than an hour or two at a time.
And then he comes across a quarry he can't resist, legal bounty or not. Someone watching him, paying too close attention, and that's enough to set loose the hound straining at its chains.
He's patient, a predator lying in ambush, only to realize too late the trap was for him. He mistook his target for prey.
Hunter should have known, in the end, it would be a Jedi.
thinking about how the (greek) big three swore to never sire any more demigod children because those children are just too powerful (dangerous) and also thinking about how the characters that, arguably, seem to have the greatest proclivity for cruelty in the name of justice or vengeance are also the (greek) big three children... there's something there, a connection to be made I'm sure of it
