Loki could have done many things to avoid the questions Emma was posing him. He could have simply disappeared, for starters - it would be no effort at all to send his shape back home, or to Iceland, or anywhere else he wished to be. Alternatively, he could have presented a distraction - used his magic to create one, or perhaps use the last thing she had said - the bit about checking in at night - and changed the subject to that, instead (night was the best time to check, it was the time he worried more, of course he'd come at night, before). He could also simply lie.
But he did not want to. He wanted to explain everything. That did not mean that he could, of course, but... it did present an alternate option.
"It... yes," he responded, edging back away from lies and half-truths and into the dangerous territory that was honesty. He dropped his attention to his hands, in his lap, as he continued. "Yes, that is why. There is... I do not know if it is truly a threat or not, I suppose... " He looked up, and for a moment he was quiet, watching his friend and her child - his goddaughter, as strange as it still was to have that title, to have been given that place in anyone's life.
"I have been made literally incapable of explaining, Emma. Of speaking a single word that could reveal what is truly at hand. That, alone, makes me... wary."
It was the most he'd been able to say on the subject, between the strange control over him and the feeling that if he said too much there would be consequences. But this still was not saying too much, was it? Dark surely would not find it anything but amusing, if he knew Loki was admitting he couldn't do anything he didn't want him to do? If the man could hear, could tell what was happening here, surely he was simply pleased to know his control was still in place, as pleased as Loki was displeased.
