"Have you had bloodwork done in the labs that would lead you to believe you have substantial medical problems?" asked Siobhan, keeping things as practical and professional as she could be.

"There. Sensory overload is taken care of, at least," she said, finally removing her hand from his arm. "Try to shut your eyes and focus your mind on something peaceful. A still lake, a candle's flame, the moon...whatever personally brings you peace."
Of course, her coping strategy might not work for him, but it was worth trying.
