okay so like. i do personally agree that seven doesn’t need to come back to the main group, and that although she can’t meaningfully be held accountable for her action/inaction when she was a child and when she felt like she had no other choice, i feel like that’s irreconcilable with the fact that six and her immediate family have always been her priority, which directly led to zenith’s Literal Entire Culture being wiped out, and obviously no matter how much closure phoenix gets, she’s still probably never going to look at seven the same.
additionally, while being alone with no one but the boat, seven can be assured that she will neither be hurt and laden with so much responsibility, and she’ll never be the cause of so much hurt again
THAT BEING SAID; in the event that seven wants/needs to reunite with any of the hunters, please consider the comedic potential that is the fact that the character (human character, since dog is old as dirt and has probably seen some crap, making what seven did small beans to him) with the least baggage with seven is. thorn/mica.
this is hilarious for several reasons, not least being the fact that thorn is canonically just one of the most unbearable people alive. even with his friends — especially with his friends. phoenix zenith, and dog, his three current closest friends, are all people who found him annoying as hell at first. during that scene in the cave with the blind cave elder, they’re all side eyeing him hard because they know if their plan hinges on being polite, he’s going to be the lvp for a while. imagine being seven and to try and ask for forgiveness from people who hate your guts, your mediating method of communication is this guy whose superpower is being a pain in the ass. unreal.
additionally, that’s not even getting into whatever their relationship was before that. thorn is the guy who liked — and then got rejected by — seven’s brother, who is now dead. don’t you think their relationship would have been awkward before all the seer stuff as well? like, thorn also had that hatred of magic, and saw seven’s power as creepy before she revealed all that stuff. and i definitely think that out of him, six, and phoenix, thorn was the one seven felt least close to out of the group.
now that six is dead, by the way, how do you think that’s going to go? i got the notion that thorn was a bit angry that seven “let” six die, but i think all of them can sense that six was her initial priority and that if she could endure six’s survival while letting them all die she would which is…also awkward…but yeah, it means that can’t really be something thorn resents her for. furthermore, six was her brother, and what was he to thorn? a close friend? a failed romantic prospect? i just can’t see a world where thorn decides that six was not as important to seven as he was to him
so the last kicker is this: imagine being seven fireborn, and you’re walking up to who is probably the most irritating person ever, a person with whom you had a lukewarm and awkward relationship before, with whom the only thing you have in common is your dead brother, a guy who he had a crush on and who he got rejected by. you go up to him and call him by what you think is his name, but he goes “actually, i changed my name,” and when you ask him what his new name is, probably not expecting the former secret name of your now-deceased brother when he was a child and when you first learned that entire tribes of people would have to die for you to plan to save the world, he says “it’s mica.”
