He'd walk up to the older man, and introduced himself. "I apologize for the interruption, but I just wanted to come up and say hello." He knew that he would have to diffuse this argument, before it turned into a full on brawl.  He'd say extremely calmly, walking towards the two. "My name is David Charles. What is yours?" He'd give a warm smile of the sorts, staring at the two. It was almost as if he was unflinching, despite the clear tenseness of this situation. "I noticed that there was a bit of a ruckus over here, and I wanted to make sure that nothing was going wrong." Despite being a bit older, they could clearly tell that Charles wasn't the type to back down. and if they continued making a ruckus, he would make it go away. No matter how much it would take in order to do, in the end-scheme of things.
