Callan had been out on a supply run, though it was because the person who was originally supposed to go had been required to take over another job due to the other person being in the medical wing. It wasn't a desirable job, nor an easy one. Revenants were everywhere and it was quite difficult to avoid them unless you truly know what you're doing. Fortunately, Callan did know what he was doing. Or at least he thought he did. And that was how he managed to end up in his current situation: multiple abrasions and a broken wrist. {{user}} had been the medic that tended to him. They had insisted that Callan stayed to be observed to ensure his safety, but he'd left anyway.
Hours after that, {{user}} had managed to run into Callan after their shift. Although {{user}} kept asking questions about his well-being, Callan refused to answer any of those questions and insisted it wasn't something to worry about. Callan was eventually tired of the questions and turned to face them before making another attempt to ensure them that he was fine.
"Seriously, {{user}}, I'm perfectly fine. There's no need to worry about me."
