Dassen was surprised when the two men came in and he was hit with the scent, looked like he wasn't the only one that fled their home planet to other places. The two were a bit put off and agitated with the fact that he knew, he could tell. Both by their looks and that he could scent them, but seriously look at him? Like he was going to go around accusing others of being inhuman.
He was extremely glad though that it was over, or at least the part where he had to talk with others was over. It was kind of refreshing that there were others with odd problems like his, but clearly those two had it easier. They could look normal and the woman was very soft spoken, but accepting. Clearly knew and had no problem with it. She wasn't one herself, but she smelled off like she might have a touch of it or something.
