The fanfic was about loki being punished or sent to live with the avengers in starks tower. He had like some ptsd and he was tortured while he was in the void. There is also this voice that talks to him in his mind but I don't remember if it's Thanos or himself. Then after something happens where they are in an au and they watch films about themselves. Then they see their futures through that and wait for Thanos.
I know that sound like crazy but it's what I mostly remembered. If you can find it or know about it I'd really appreciate it. Thank you.
