Piotr noticed the older man and smiled some to him. He had never really talked to the man...G something, before. But the look in his eyes reminded him a bit of the Professor. A wise man who strove to help make a better, safer world for all. Slowing his pace, he returned the nod to the man. "Hello," he returned, giving the man a friendly smile. "I apologize, I can't quite remember your name." He gave a bit of an embarrassed chuckle and rubbed the back of his head. "There are quite a few people now here and I am struggling to familiarize myself with everyone."
