Emlyn grinned proudly talking about his sister, and some of that pride leaked over into Auriel's mention of his own brother. For a moment though, and only a moment did this happiness last. His smile quickly soured, and he shook his head as if to regain his composure. He might have snapped at Auriel even, as if from nowhere, but the oncoming turn of attitude was cut off by an even stranger occurrence.
Auriel brought it to words a few moments after Emlyn had noticed it. The ground had indeed moved, or at least it felt as though it had. He balanced himself against Mirror, looking around. He filed through his mind for anything that fit the circumstance, and all sources came up Grimm.
He was not mistaken. At the sight of the Datura, his eyes widened in shock. It looked damaged? Or old perhaps? He wasn't sure, his mind was buzzing too much to hold on to a stable thought for long. This was no minor enemy, no spry Itzamna to outmaneuver. This was a monster by definition, a terrifying beast that could, if it chose, destroy them. And yet it chose not to do so. It spared them only a passing glance before lumbering on, like it was searching for something.
Emlyn felt his hands shake, and it was a few moments before he caught them, and tried to steady them into fists to little effect. He gulped, clutched Mirror tighter, and looked to Auriel. Dammit, why did he look to Auriel? He was in control, he didn't really need this other boy. It must have been a reflex, simple as that, a reflex to...to make sure his ally was alright, yeah. He had to double check on him. Just in case.
"W-we should..." he cursed himself for stuttering a bit, but the way he was still in control, still able to craft his words and his tone into a suggestion. He made himself sound as if he were going to issue some sort of command, but still left room for Auriel to finish it with, what he hoped, would be a good plan.
