Darcy wasn’t sure how anything about this situation could be considered relaxing, and turning his mind off felt like an impossible task. He very reluctantly closed his eyes, but did open them again when she climbed onto him.
“Really? What on Earth are you doing?” he asked in confusion. It wasn’t something he had experienced before. He did stop taking, and closed his eyes again, decided for the moment that the important thing was that he trusted her, and if he asked her to stop it he knew she would without getting upset about it.
As a person, he was generally beyond tense. Although it was getting better on the station, he knew that he had a long way to go before he was anywhere near... whatever the term TK had used was. Chill out?
