Summary: They’re twins. Fraternal, obviously. Thor is nine minutes older.
In kindergarten everyone assumes they’re cousins. Thor instantly corrects them, loudly asserting, “He’s my brother.”
High School (and beyond) AU.
As far as Thor can tell, Loki never sleeps. Thor wakes and sees his brother sitting there in the other bed, eyes reflecting the light from the tiny reading lamp he has clamped to the back cover of his book. Sometimes Thor can hear the floorboards creaking as Loki goes wandering around the house in the dark. If Loki isn’t reading in bed or pacing downstairs he’s in the other room writing and drawing. Thor can see the light under the door. He can hear Loki pissing at three in the morning. Hear Loki sobbing in the shower.
