There were... voices. Two males. Clearly come to investigate the crash, though he did not recognize any part of their speech. It was a primitive language, to be sure, but one that he did not recognize. When he was rolled onto his back, he knew instinctively by the manner in which he was moved that he was being checked on. For if he had fallen into enemy hands, he imagined he would have been treated much more forcefully.
Reaching out abruptly, he touched the forearm of the man nearest to him, opening his eyes slightly as he did. The sight that greeted him was not at all what he expected; then again, it was not as though he had seen anyone from his planet up close before. Still, though, he had not expected the mask. Zod could not help but wonder if there was a reason that he hid his face.
Not having the words, Zod gave the forearm of the man a couple pats, trying to convey his appreciation for whatever aide was to come.
