"That's not a bad idea, actually," Lex said after he'd thought about it a second. The risk of being seen, or at least heard, was pretty high. Their footsteps echoed pretty loudly in the otherwise deathly silent stairwell, so if anyone happened to be around the bottom of the steps, their cover would likely be blown. So on one hand, their cover would be gone. And on the other hand, painful and agonizing not-knowing. At the end of the day, he'd rather lose their privacy than lose more time that he should by rights spend looking for his mother.<br/><br/>Lex picked up her hand and pressed it to his lips as he decided to sign away their privacy. "Show me to that radio again?" he asked nicely. It was still too soon for him to appreciate the tallies that apparently marred the walls, but at least he could get a general sense of the room at the top of the tower. Maybe he could even hear his mother's voice again, though he wasn't sure that he wanted to. The more of her voice that he heard, the more the military was apparently interested in her. The question of 'why' had been plaguing the back of his mind ever since he'd heard her ominous warning, whatever it might have meant. And if that was pre-recorded audio, why had she addressed him so... directly? It was like she knew that he was listening. His mind would be put to ease if he could just replay the tape that had started the last time he and Blue were up there, but for now it was the not knowing that killed him.
