It dawned on Nathan as soon as Jacen mentioned his name, and his sister. It was like everything clicked back into place and he remembered that was why he had recognized him. Without trying to make a big deal about finally remembering, he went on, "Nathan Howard. Nice to meet you, under the circumstances, I guess." He had been keeping his focus on Jacen more than he had been on where he was going, so he looked up to make sure they were at least heading in the right direction. After all of that, he didn't want to be taking him the wrong way. That would just be annoying and could probably cause Jacen further injury. Anyway, the nurse's office wasn't much further.
Speaking of nurses, was Nathan the only one to think it was weird to have a male nurse in a high school? The hospital, maybe, but a high school?
