swiss is the one who remembers most.
many of the others have blocked it out—trauma repression, cirrus told him once, so they can survive in this new world. those that don't, don't usually like to talk about it. adjusting to the new form, learning how to use the abilities, it's all so much so quick so loud so bright so much, they don't think about it if they can help it.
except swiss.
swiss remembers. he remembers the pain, he remembers the aches in his new muscles and the burn of his new abilities and the deafening noise of the mortal world, new and exciting and terrifying all at once. swiss loves it, loves the way he can do so much and no one bats an eye, really, but he remembers.
so when phantom comes, swiss is there, waiting. he's got heat and ice, soft blankets and firm fingers, rubs sore muscles and soothes the ache of being in a new home. it's not instant, of course, because phantom is...different, they're all different in their ways, so he waits like he always does until phantom comes to him. they talk and they laugh and they cry and when phantom asks if it's better here, if it really is worth it like everyone says, swiss is ready. he just has to tell the truth.
and if it means phantom is just as onboard with all the wild shit swiss does, ramps everything up to eleven because why not the way swiss does, prepares for summonings the way swiss does...well.
swiss can't help but smile. because he's not alone anymore.
