A while ago I made a post about how we have Legend fearing everyone else is a dream but we should also consider Time fearing that all of them will forget about him.
Imagine that one day Legend wakes up in the middle of the night after a nightmare about Koholint, Time was on watch and went to comfort him. Legend throws himself towards Time and hugs him hard, wanting to hear the old man breathing and to feel the comforting warmth of his body, trying to grasp the fact that maybe Time is real, maybe he's here, maybe he does really have others at his side and he's not alone.
The next morning Legend apologizes with Time about what happened, but Time gives him a side hug and confesses that it's ok. He has a similar fear too. After leaving the Master Sword on her pedestal, during Termina, everyone forgot about him and even if he loved them as close friends, they only saw him as "someone they knew". So Time tells him that he fears that one day, the chain will forget about him, that he won't be "their old man" but just another hero they know.
And both heroes make a promise then. Time promises Legend that he's real and Legend promises Time that he's never gonna forget him. Both know is an impossible promise, a dream doesn't realize it's not real until it disappears and someone can't remeber something that it never happened. Yet they make that promise to eachother, as a way to reassure their own heart, like if promising something in exchange will fullfil the other promise.
Since then, when Legend feels nothing is real Time is at his side hugging him and helping Legend look at the surroundings, hoping that his touch let the veteran know he's real, and his voice calm that grumpy heart. And when Time fears nobody there knows him, Legend is holding his hands between his, repeating his full name and title again and again so Time hears how he didn't forget, but also Legend tells him about a happy memory where everyone is included because there's a memory to cherish.
