Link marched into the second floor hallway cautiously. He wasn't surprised that it looked almost exactly the same as downstairs. Everything looked the same, here.

"You're going to have to tell me where to go... I will cover you." Link was at least confident that he could defend them, if the need arose.

The next hall was long, and didn't have many doors. The bigger doors toward the middle were shut, which seemed to suggest that nobody had passed through, but Kyousuke still made sure to keep on the alert for anything unwanted. So far, at least, they seemed to be completely alone.

"It should be past those doors, at the far end to the left," he informed as they walked. He was really beginning to dread this... He was convinced that the only thing they'd find in the morgue was a confirmation of what they already knew. Hope was fine, but it was difficult to hold out for something that seemed so impossible.

They'd already neared the Sun Room and the door that led to the building's exit, but Castiel wasn't aiming for either one tonight. It was still quiet on this side of the building, which seemed strange to him. He was using crutches, after all... He would have expected that plenty of other patients would have beaten him and Lust to this point.

It didn't matter. If their path wasn't littered with obstacles, that would make it easier to reach the greenhouse. As for Lust's question...

"There is one person I know who I believe is still ill," he explained. "Her name is Aigis. She used to be an android, though she's been made human here." Just like him, and perhaps just like Lust. Though she was a created human, so he had no idea if she could ever be the real thing. Did she even have a soul? There was no way he would be able to feel for it in this place; he didn't have that kind of power at the moment.

"We have a few things in common, but she hasn't been taking her illness very seriously." Which frustrated him, especially since she had struck him as the goal-oriented type. Did she really have that little concern for her own well-being?

As Link pushed open the doors into the northern end of the hallway, his heart began to race. A nervous energy came over him. This was it. All or nothing. Either Sora was here and he was alive, or all hope was lost.

The hallways seemed so much longer in the dark. Every shadow felt like a threat. And with the rush of adrenaline leaving Link's heart pounding in his ears, he was almost imagining seeing things. He kept reminding himself to keep his cool, but goddesses help him, it was so difficult.
