Rin ain't feeling too good with all the angst I'm writing ahaha
7So yeah.
Major spoilers and possible triggers lie ahead. Please be cautious.
Rin got his vision, the moment he escaped the place he was trapped in. He was though, the only survivor out of many, many children. When he managed to get back to his senses, he began searching the ruins, and dragged out one by one, each body of his "friends". He didn't bury them, but he made sure that when someone eventually found them, no one was forgotten. He didn't have time to think about them. Rin was too busy trying to attack the Adepti and "take revenge" for leaving him in their blind spot.
Nowadays, after he cut off his connection to the Fatui, he visits their graveyard daily. He'll tell them stories, bring their favorite flowers, and update them on how the world is doing. He spends most his time there, knowing that none of them are going to return. He just innerly hopes that they have heard him, and wishes that someone, just one, is still alive out there.

Perhaps, that one is waiting for the right time to greet him.
That time isn't yet though..
