"Link! Listen!"

"Omigosh I got a big one!"

The Hero of Time started reeling in his fishing rod, ignoring his faerie's plea.

"Link!"

"Almost done, Navi, I'll be right there."

"LINK!"

"Dammit it got away."

"Link, stop wasting time, you've got a kingdom to save!"

"Can't I have just five minutes to relax and catch some fish? Five minutes isn't going to make the difference between saving the kingdom and losing the final battle against Ganondorf."

"It hasn't been just five minutes Link! You've been out here for twenty, and it would have been a lot more if I hadn't interrupted you!  At this rate you might not show up for the fight against Ganondorf until seven years after he's already won!"

"Ganondorf isn't THAT powerful. He's just some thief from the desert. I'm sure the Goddesses have contingency plans to stop him from obtaining the Triforce if I don't show up in time."

Later...

Link yawned and stretched. "That was a nice, short nap. Time to go face Ganondorf..." he paused.

"My body feels REALLY weird."

"Welcome back, Hero of Time. After your seven year slumber—"

"What!?" Link gasped. And then...

"You mean to tell me that I seriously slept through Ganondorf's takeover of Hyrule?"

"It would have happened anyway," the Sage told him. "The Goddesses forsaw that you would sleep as Hyrule screamed, and so devised a plan to make sure you could still save the kingdom even if you forgot to show up to the final battle. As the Hero of Time you have lived many lifetimes, many of them remarkably similar. So it is natural that sometimes you would have trouble paying attention or keeping track of it all. It is for this reason that the Goddesses sent Navi to you, just like they sent you Fi long, long ago."

Link stared at the old sage.

"And whenever you want to go back in time to your younger self's body, just return to the Temple of Time and play the Song of Time on your ocarina to open the Door of Time, then place the Master Sword back in the stone."

That was kinda creepy, now that Link thought of it. He'd been asleep for seven years, so he shouldn't feel seven years older. And yet he did, as if his mind was replaying the wisdom of his past lives while he was sleeping.

Maybe he'd been through it all before, and so his mind was filling in the blanks in his memory from age ten to seventeen and maturing his physical brain without newer, more recent (and therefore more fresh in his mind) experiences to reinforce the life lessons.

He wondered if going back in time to his younger body while sleeping would be equally disturbing to the point where it distracted him from all the life lessons he'd relearned? That would surely make him forget the wisdom of his past lives.

On the one hand that seemed kind of like dying, but on the other he was sure he'd been through it SO many times before he wasn't sure that really mattered to him as much as it should.

He figured he would remember it all eventually either way. Probably. Still, he thought that he might as well try to get used to the transition, since he was going to be traveling through time a lot.

Hero of Time indeed. The Goddesses had a sick sense of humor.

"I think I'm going to head back in time now," Link told the sage. He reached into his pockets.

"Shit! Where'd I put my Ocarina?"
