Jack looked at him in confusion as Arvo stuck out his hand to shake hands, he wondering for a moment if this was some cruel joke or a simple mistake. Probably the latter, judging by the fact that the other was also in a leg brace [this made Jack wonder if the front office had put them together for this similarity alone] Jack didn't think this guy was the kind who would make a joke out of someone else's disability. 

Instead of ignoring the hand he stuck out his left hand instead, "I-I apologize for using the incorrect hand, but-." He said, wiggling the stump of his right hand, hidden by hoodie fabric. 

The front officer workers then told them they better get going, so Jack nodded and wordlessly opened the door and began limping out, telling Arvo wordlessly to follow. 
"So, you're from...Russia?" Jack said, trying to make small talk. He had never been good at small talk, or talk in general. But, if he was going to be showing this guy around he might as well try and make a friend, why not.
