His brow furrowed a bit as he glanced around in an attempt to answer her question. He didn't see anything that resembled a communication device, or at least one that he was familiar with. He was just about to admit that he really wasn't sure when, once again, logic managed to come to the rescue.
"If our location resembles turn-of-the-twenty-first century Earth it would seem only logical that means of communication would as well," he stated, sounding far more sure of his deduction than he really felt. Averting his gaze away from her lest she see the uncertainty he was actually feeling, Spock scanned the room with this new perspective in mind. Again, however, he came up lacking and very nearly sighed in frustration.
"There must be something," he muttered, his young age and imperfect control over his emotions at long last shining through as he all but stormed away from the window and toward the nightstand beside the bed. "You do not abduct two children, place them in a location this large, and not give them some sort of means to-"
His mini-rant was cut short when he yanked open one of the nightstand drawers and at long last found what he was looking for. Were it allowed, he would have smiled. Instead, he merely plucked both of the small, handheld devices from the drawer and held them up for Nyota to see. Granted he had no idea how to use them just yet, but he was almost certain they were meant for communication. They certainly resembled a very archaic version of the newly-constructed communication device that his Father had been discussing with one of his colleagues not long ago.
Spock's gaze locked onto Nyota, triumph shining in his brown eyes as he held one out for her to take. This time he didn't even bother to try and suppress his emotions fully. He was going to enjoy this small, but nevertheless fulfilling, victory for just a moment longer. Then he'd go back to being a proper Vulcan.
