"Probably pork, that's the cheapest meat." He picked up his cup with pills and pushed his chair back. "I'm going to return these. And maybe see what that frowning and altering the list was about. I'll be right back."
He crossed the room and went straight to the medicine cart. When Marc noticed he was approaching he took place between Benjamin and the cart, in case his attentions weren't good.

"It will be a waste to throw them away," Benjamin said, handing Marc the cup.
"True," Marc said as he took the cup back. "Feeling a bit rebellious today, Benjamin? To hand me the pills publically?"
Benjamin hadn't thought about that, but he liked the idea. "Maybe." He glanced at the list on the cart, looking at the crossed out name. "I didn't see Susanna yet," he continued. "Do you know where she is?"
"I just called and was told she has gone home. She took her meds. You see what happens when people follow their treatment?" Marc wouldn't leave any opportunity unused.
Benjamin made a derogatory noise. "She traded them for painkillers most of the time. Bet you didn't know that." He turned around and quickly walked back to the table with Ray. His expression changed to worry, something he had been very careful to not show to Marc.
