Tyren was distraught. He was coming to rely too much on Caaliey, he realised. And that was not good, especially since he didn't want her involved in his quest to find his parents. He was already a wanted man, and he had no intention of adding her to the Shinra's elimination list. He could excuse the fact that she fought alongside him by reasoning that he could have taken on the creatures alone.
But needing her to cure him, that was a completely different matter. It meant that he depended too heavily on her, that without her, he wouldn't have made it. It was the reason why he had been so insistent that the wound be left alone. Even then, she'd had her way in the end. If I'd been thinking straight, I'd never have let her. A more logical part of his mind said to him, You were light-headed from the loss of blood. And if she hadn't healed you, you'd be dead because of it.
He kept his eyes shut as he heard Caaliey laying out her own bedroll on the opposite side of the fire. Unable to resist the urge, he opened his eyes slightly, and noticed she carefully kept her back to him at all times. She's mad, all right. Who'd have thought she'd be so damn sensitive? He sighed silently. It wouldn't be a very pleasant journey tomorrow. I'll apologise tomorrow, I suppose. Getting to Junon would take much longer without a chocobo.
