Setsuna didn't, at first. He had noticed her there, and figured she was resting, so he left her alone for a little bit. It was when he finally noticed that she was still there that he went over to check on her.

When he realized she was asleep, he was of two minds as what to do. On the one hand, she clearly needed the rest, and he didn't want to disturb her. On the other, this wasn't the best or most comfortable place for her to sleep.

He knelt down next to her, and ended up giving her the same perturbed look that he had been giving his Gundam moments ago. Something was different about her... or maybe he was just seeing her in a different light. She was the same as he remembered, but something had changed...

His eyes were drawn to her hair, and without thinking about it, he reached out and brushed some of her hair away from her face. It was a simple and kind gesture... and so unlike him that the moment he realized what he was doing, he briefly froze, then snatched his hand away. He started at it momentarily, as if that limb had somehow betrayed him.

He opened and closed that hand a few times, as if testing to make sure he did have control over it, then lightly shook Feldt on the shoulder, to try to wake her up.
