After his revival, being surrounded by people he doesn't know, Revali clings to the people from his past. Most of the time, this is Link as the Hylian is at Rito Village a lot. Despite how he still doesn't like the knight, being near Link is grounding.
Link is confused by it at first, but doesn't push Revali away. He understands the feeling of being out of place, especially in a place that used to be home. So he doesn't say anything about the Rito tailing him like a duckling to its mother. Or when Revali grabs his hand, squeezing a little too tightly, as the children run past them in excited play.
Link doesn't question when Revali asks him to stay the night in his new roost, instead of sleeping at the inn. He allows the Rito to pull him into the hammock, laying against Link with his head on the knight's chest despite their difference in height. He doesn't say a word when he starts to run his fingers through the warrior's hair, ribbons and beads sitting on the shelf on the other side of the room.
He doesn't complain when Revali's hold on him becomes just a little too tight. Neither of them are asleep, if Revali's mumbling is any indicator — the Rito quietly repeating that this is real, they're not dead, the Calamity is gone, Windblight can't hurt him anymore.
Link holds Revali a little tighter, the other letting out a shaky breath, a whispered "thank you" leaving a trembling beak. An apology spoken so softly, Link almost misses it — he knows why Revali says it, even if he doesn't remember their strained relationship.
"Let's just start over, okay?" He responds.
Revali doesn't say anything, but if his reach for Link's hand was any indicator, he wanted to start over, too.
