Trevor had been traveling by himself for quite some time now and when he was met with you and a little girl named Cynthia traveling by your side a few days ago, he had to grow accustomed to traveling with two extra people.

He was on his way to Gresit and as were you and Cynthia. He figured the least he could do was stay by your side until you all made it to Gresit since you saved him from getting into a bar fight.
