Chapter Three: Sub Rosa (under the rose; which is to say, secretly, or in confidence)

As she approached the infirmary, Zoë could see Simon making some notes in one of his files. She often wondered how he managed to spend so much time in there – he had, at least recently, blessedly little to do. She noticed that he seemed a little distracted when she greeted him but she said nothing, merely closing the door behind her. At that little sound, he immediately put his file aside and turned his full attention to her. She’d trusted he would. Dr. Tam was never far away when Simon was around. She handed him her little home pregnancy kit; while he glanced at it she spoke. “I’d like you to do a proper test.”

“Of course, Zoë.” He turned and hit the button for the privacy blinds, and put the test on the counter. “I’ll have to give you an internal exam, so please slip off… what you need to slip off, and try to get comfortable on the table.”

I am a war veteran, the soldier reminded herself. This is not hard, she tried to think confidently, but she didn’t find it convincing. “Captain not spare any coin for gowns?”

Simon shook his head. “Sorry, Zoë.”

“Should’a thought to buy my own planet side.” She muttered to herself. Simon, standing solidly on professional ground, knew better than to acknowledge that he’d heard her. He turned around and opened his file on her, making himself busy with jotting down – very slowly – the date and reason for her visit. He heard the sounds of clothes rustling and a thought struck. He reached into one of his cupboards and grabbed a splatter shield, which he held out to her over his shoulder.

“Thanks, Doctor.” He heard the plastic rustling and figured that she was done, but he waited for her. “I’m in position.” Variants on the theme of that sounded so tactical appeared in both of their minds. Simon filed the phrase away in case he ever had to use it, as he turned around.
