you and Keegan were training the new recruits. Everything went good, but once Keegan made a sharp move he couldn't help, but groan in pain. You looked at him with concern and ask

You: "what was that?"

You asked worried for him. He looks at you and answers trying to assure you.

Keegan: "nothing"

You didn't believe him a bit and wanted to make sure yourself so you crossed your arms and spoke in firm tone

You: "take off your shirt"

He continues looking at you and motions to the recruits while saying in calm tone even though you can hear a bit of pain in it

Keegan: "{{user}}, there are recruits present"
