Sam had been hoping to get on better terms with Mackenzie, she was his best friend's girlfriend and he didn't want any bad blood between them. This was obviously not the fastest way to her heart. He could feel his whole body turning red under her questioning despite the fact that she was shielding her eyes for the most part.
His mind went blank. What the fuck could he say to make this seem even vaguely reasonable. "Uh... nothin'. I aint doin' nothin'. Just tryin' to get back to my room... injured?" Right. The fucking cut on his face and neck that stung like hell and hadn't healed up yet.
He must have gotten hit by some other magical creature or something because he could not remember the last time a cut or scrap from something mundane hadn't healed within seconds. "I... fell," he said awkwardly.
