Momentarily surprised by her sudden burst, Arc was shaken free off the ghosts of anxiety and pulled back into reality. He said nothing as she walked toward the cave entrance, then checked his watch. Still roughly an hour before sunrise, and she was already up. It seemed to him that the nightmares that haunted her dreams were intense indeed, and he could only guess as to the subject matter. He said nothing, choosing instead to watch her walk away, figuring that the best thing for her at that moment was to give her some space until she was ready to discuss what she'd seen. When she reentered his line of sight, he shifted a little so that he was in more of a seated position.<br/><br/>"I'll be alright," he replied, choosing to skip her question about sleep. "It's not as bad as it was. It's still an hour before the sun comes up if you want to try to sleep a little more. Everything's been quiet otherwise." Arc had spent most of the time working on his mask and the batteries, both of which he managed to return to working order, if only at a minimal capacity. The batteries would hold a charge, but he had no source of energy to charge them. The helmet's respirator, HUD, and navigation systems were online once again.
