Marcus found it sitting on the desk next to his copy of the daily duty rooster. He knows it was placed there deliberately and wasn't just forgotten in the rush of the early hours to begin the day. He picks it up and slips it on his finger; it only reaches the first knuckle before it can't go anymore. He wants to discuss with her. Wants to make sure she's okay. Most importantly to see if she was ready. He knew the answers to all of them. It would be best to leave it be.
"Hey Abby where's your ring?" Marcus overhears Raven casually asking a few hours later as he passed by. He stops remaining unseen to watch it play out.
"I decided it was time." Abby simply replies looking at the freshly bare left hand. He sees Raven nod knowing she also understood not to explore further.
