What if Yasuo's brother is alive

Yasuo spent the next several years wandering the land, seeking any clue that might lead him to the murderer. All the while, he was relentlessly hunted by his former allies, continually forced to fight or die. His mission drove him ever forward, until he was tracked down by the one foe he dreaded most – his own brother, Yone.

Bound by a common code of honor, the two warriors bowed and drew their swords. Silently they circled one another under the moonlight. When they finally charged forward, Yone was no match for Yasuo; with a single flash of steel he cut his brother down. Yasuo dropped his weapon and rushed to Yone's side.

Overcome with emotion, he demanded to know how his own kin could think him guilty. Yone spoke: “The Elder was killed by a wind technique. Who else could it be?” Understanding swept over Yasuo as he suddenly realized why he had been accused. He professed his innocence once more and begged his brother's forgiveness. Tears streamed down Yasuo's face as his brother passed in his arms.

Yasuo buried Yone under the rising sun, but could take no time to mourn.

I don't think it is gonna happen
