Link was tired, so very tired. He was tired mentally, and somewhat physically. Then again, he was like that most days (though the nights were the worst). That was why although he didn't accept the invitation to the dance, he still took it (just in case).
"It could be fun you know," Zelda had said. Link was astonished and grateful that Zelda would take the time to deliver it to him, being the Queen and all. He didn't feel worthy to have such a good friend in the castle, even if he had saved her kingdom.
Link walked over to his chair and sat down, turning the letter over in his hands. He suddenly wondered how it would look as a zora.
Barely thinking about it before doing it, he walked to his closet, ruffled through it and pulled out the bag full of masks he had collected in Termina. He found the zora mask and pressed it to his face...
...pain, excruciating pain. He felt his body contort; every bone, muscle, and ligament shifting. He screamed in agony...
...nothing, the pain was gone. He looked at his arms and swung them around, slicing the air with the blades. So familiar...
...no, this was wrong. Why did Mikau choose him? Link just happened to be there. Sure, he saved him, but Mikau still died. Did he ever even think to go back in time to try to stop the attack? Did he ever try to prevent anyone in Termina from dying? In the end, no. He was a stupid, selfish kid, who wasted so much time saving up rupees for no reason, who beat up cuccos for fun, and who left Romani to the aliens his last cycle.
He was unfit and didn't deserve to be invited to the dance.
