Why would he get hurt? Physically, if he got hurt, he knew it wouldn't be Nabooru's fault, unless she specifically warned Ganon about his hatred of him. But Byrne had a feeling she wouldn't do that. He did promise her he wouldn't kill Ganon. At least not yet. However, the minute Ganon tried anything funny, those metallic claws would be through his heart in a microsecond.

Emotionally, however, it would be Nabooru's fault if he was hurt. At least, that's what he told himself. But no, it wasn't true. It would be his own damned fault for letting himself feel anything for her, for letting himself worry. If Nabooru were to die, it would be her own fault. And he would grieve. He would grieve that her stubbornness killed her.

And yet, it was that very stubbornness that Byrne himself possessed. The path he chose in life was a result of his own desires, despite Anjean and any others trying to shove reason into his face. He didn't want any of that. It was then, as Nabooru explained herself, that he saw that younger version of himself. He hated it with every fiber of his being, but at the same time could find no fault.

It actually relieved him to hear that Nabooru was not going to let the Goddesses control her, that she was going to use that power for her own goals. He knew that she was still trying to do good instead of being like himself and just out to get power, but perhaps, just perhaps she wouldn't be swept away in the Flood. Perhaps she could stop Ganon before he obtained the Triforce.

He paused for a minute, closing his eyes and collecting his thoughts after Nabooru finished speaking. Finally he looked back at her and relented, just as he didn't want to do in the first place. "All right. If you say you won't let anything happen to you..." He nodded, showing his acceptance in the matter.
