Just me

Light arrows are a weapon almost exclusively produced by Zeldas. Tetra can use light arrows. She can shoot near infinite amount of them, which Wind cannot do. Wind’s magic drains much too quickly for more than a couple of light arrows. But Wind can still shoot them.

Hence the following theory: Wind is also a descendant of Lullaby/Sheik but from a weaker royal line than Tetra. During the Great Flood, King Daphnes might have sent his oldest daughter in one direction and a younger son/daughter with the Sheikah. The Sheikah ended up founding Outset Island and raised the youngest child of the king without any knowledge of their heritage for a secretive protection. Meanwhile the eldest daughter (I think that in times of turmoil, the king always has an eldest daughter because Demise Curse) was taken by the royal guard, as shown by Tetra’s portrait, who sailed over the seas to avoid Ganon’s detection. Hundreds of years later, Tetra was born of the eldest daughter’s royal line while Wind was born of the youngest child’s weaker line that was "diluted" with Sheikah blood.

Yeah, Wind would be a Sheikah in blood too. Would explain his sneakiness. Also he’s likely not the only Link with Sheikah blood, but I digress.

I do have second argument. And that’s if Wind is Four’s descendant, he will also likely be Dot’s descendant. Which means he would be of royal blood through Dot, and so him going through the royal line via Lullaby/Sheik would check out since what is the likelihood that in apocalyptic event another offshoot of the royal line would randomly survive?

“What on Earth are you doing?”

Wind froze, hands on his face. “. . . Nothing.”

Time raised an eyebrow and sat down on a log in front of him. “Let me see,” he said softly.

The sailor lowered his hands slowly, revealing skin angry and red from scratching and decorated with tiny blonde hairs. “It’s itchy,” he muttered, embarrassed.

Time chuckled. “Want help?”

“. . . yeah.”

“Alright,” Time stood, cracking his back. “Come on.”

Wind blinked, standing to follow Time. He was about to ask where they were going when he saw the river coming into view; the old man settling on the sand.

“Here,” Time held up a small razor. “Watch me.”

Wind nodded, watching as Time splashed some water onto his face, waited a few seconds for the water to settle, and then gently dragged the razor across his face, using the still water as a mirror.

“Alright,” Time announced, washing the razor in the water and then handing it to Wind. “Your turn.”

Wind took the razor hesitantly, then slowly copied Time, watching the old man out of the corner of his eye for approval.

“Good?” Wind asked, looking at Time as he rubbed his now-smooth face.

“Good,” Time smiled, ruffling Wind’s hair, grin widening when Wind protested with a sharp “Hey!”

Time’s laugh settled into a soft smile as Wind spoke softly.

“Thank you.”

“Don’t mention it. First shave’s always weird. I remember when I was around your age. It took me forever to figure it out.”

Wind nodded slowly. “Yeah, I. . . I can’t imagine what that must’ve been like. Figuring stuff out all on your own.”

Time’s head tilted in consideration. “It was hard,” he agreed. “But you don’t have to go through that. You have a whole group of us to ask if you have questions. And you can always talk to me, okay?”
