Zach greets the Kindred he knows and introduces himself to the new arrivals and those he does not know, and tries to keep up with the conversation he was having with Martha, but is quickly inundated with the new arrivals. He gives the Herald an apologetic smile, and shrugs his shoulders helplessly.
Zach becomes a little more shy around the numbers, especially since there are so many that he is meeting for the first time. He gives compliments on clothing and style, and makes sure to memorize all faces and voices for later. He is simply waiting for the others to arrive and the safari to start.
