The first vocals he had heard sounded familiar, at least-- they were nearly identical to those of the one human child, Miko. However, the sounds she was producing sounded nothing like what he had heard from the teenager before. From what he could recall, Miko was from a different part of Earth than the other children, and had mentioned it on more than one occasion. Were those her native vocals?
An unfamiliar set of vocals filled the line, cutting off his train of thought. Skyfire's optics narrowed as he listened, their words harsh and accusing. Perhaps he had been cut off from outside contact for far too long, but he was not going to stand by and allow this stranger to speak the way they were.
{{ I beg your pardon, but I do not know who you are. }} His vocals were even and steady, accented only by a rumble of displeasure from his engines. {{ I have not been in contact with anyone for the past few cycles, and do not appreciate being yelled at for things I do not have control over. Now, is there something you require of me, or are you going to continue your ridiculous accusations? }}
