sorry, i'm just busy thinking about a linked universe au where after their journey, each link goes back to their eras and lives the rest of their lives mostly in peace. except after they die, they get to witness and guide one another on their original journeys.
imagine Sky peacefully falling asleep surrounded by kids and grandkids and Sun, only to open his eyes in an unfamiliar land. except he's been here before, this is Four's era! and look, it's Four! but a much smaller version of the smithy he knew. he tries to call out but suddenly becomes aware of his ghostly form and it's inability to form words. no matter, if this is the time and the place and the hero he knows, Sky will do everything he possibly to help his brother. it's nothing major. just a rustle of the grass when he's looking for rupees, a few seconds of extra strength fighting enemies. a redbird's song warning of a storm, a ghostly hug the boy(s) will never feel after the final battle with shadow...you know. at one point, Four does disappear for a few months. Sky's not worried though. he knows exactly where and when his boys are.
then, finally (yes finally, Sky is trying his hardest not to sound too happy, but finally) Four awakens next to him. Sky greets the boy with a hug he can feel this time. the Vio in Four starts connecting the dots, and in Sky's arms, he begins to laugh. Sky pulls away, worry etched on his not-really-there face. Four grins up at him and simply asks "who's next?"
