Loki was not unaccustomed to playing listening ear to others’ problems - he had a way of coming across as sympathetic, and it was something he’d often used to his advantage, prying secrets and troubles out of people with well-placed words, subtle inflection and carefully calculated expressions - and then turning around and using them to do whatever he wished, from spreading dissension and gossip, to playing jokes - to helping out with the problems others divulged to him, in his own roundabout way. His expression was schooled into one of vague curious concern, now, hands folded behind his back, letting Clark speak.
Inwardly, Loki was mentally reviewing the spell he’d used on the boy - Kon - and trying to determine what the risks of having used it on him were. As far as he could recall, there was nothing dangerous about it. It was just sleep, after all, and everyone slept. Sure, it was sometimes possible for the spell to linger a little, making the one who had been rendered unconscious a little groggy, afterwards, but it hadn’t seemed to in this case - and it wasn’t a delayed response like this would have been if it were a result of what he had done - nor had it ever caused a breakdown, as far as he was aware.
Clark was apologizing, then, and Loki offered a sympathetic smile. “There is no need to apologize, I assure you.”
He waited a moment (it wasn’t hesitation, per se; it was an intentional pause to give himself a moment to think), trying to determine whether the question he wished to ask was a good idea or not. On the one hand, it would be beneficial to be honest in his suspicions that he may have had something to do with this problem - because if it surfaced later and he had not said anything, it would clearly imply he was hiding his involvement. On the other hand, just broaching the subject may place him front-and-center as a suspect in this strange event, and it could undo the entire image he’d been trying to display for everyone - an image of someone who was not a threat.
“Do you suppose this could be related to the recent events with Famine?” he asked finally, tone very a careful neutral edged in curious, no inflection to suggest that he thought it might be so, to suggest he felt responsible. It was just a question. His hands remained folded behind his back, his posture both straight and casual, as though the answer he got in response was of no concern to him.
