She took in the situation, frowning, and approaching the elderly man. "I know first aid," she said, keeping her voice calm and steady. The first step was to remain calm and to hope that the other person took their cues from you, she knew. "I'll do what I can until we can get you to a doctor."
She probed gently, talking all the while as she did in that same calm tone. "I'm going to check for swelling, fractures, or anything out of place," she said. "Let me know if it hurts."
He gasped, which was odd as she was probing nowhere near his shoulder just yet. Clarice looked up and saw an expression of shock rather than pain on his face and turned automatically to see what had caught his attention. The man who had called her over was now about twice his original size, shirtless, and appeared to be made of metal.
Clarice barely caught her own strangled gasp of surprise and turned it into a clearing of her throat. This place was strange, and she knew that. This man was no stranger than Kuvira and her powers, and he was helping this elderly couple. "Sir? I'm going to need you to tell me if this hurts," she said, pressing gently at the front of his shoulder.
"Ouch, dammit!" The old man's attention returned to her as he flinched back.
"Okay. Sir, I know it hurts, but how much can you move your arm and fingers?"
"He just turned into a giant statue and you're asking me to move my fingers?"
Clarice frowned. "He's moving, which doesn't make him a statue. Please move your fingers, sir."
The old man did as she asked.
"Good news, I don't think it's broken. It's probably sprained, though you'll want a doctor to confirm it. And you'll want a doctor for some painkillers, I'd imagine." She gave him an encouraging smile, then turned and smiled back over her shoulder to the man, now no longer metallic. "Thank you."
