It was the first time while watching the log that an Eno was looking for another. With the knowledge that Logan knew he was trying to piece things together. Was the Eno a vampire family? For some reason, they were looking for each other, either the first man or someone different.
Logan didn't know much about the Vampires, at the time he wasn't too interested in it and would let Quinn deal with that stuff, but maybe the two of them would soon need to have a talk to figure this out. It was because of this very reason that Logan had no clue about the Eno family and their relation to Quinn.
His parents had gone through all of the Eno's names that the Green's dealt with, but Vincent wasn't one of them. When the man asked for them to describe this Eno, he had a disappointed look on his face. After that, the man left for a while, and the Green's continued their life as usual. Never learning of this Eno's name.
