Kon was relieved to hear Frey suggest that the other two with him wait outside. He didn't honestly think any of them would freak over seeing Kurt but Kurt might not be too happy to see even more new people. Even if it would be good for him to see that no one was going to be scared of him when they were locked in a crazy prison with monsters and stuff. Smiling at Frey he said, "Look, before you see Kurt I've got to tell you he doesn't look the same at night as he does during the day. He's still the same guy, he just.... looks different. OK?"

That really covered it and there wasn't much else he could do except be ready to kick the guy out if he was the sort of loser who disliked people who didn't look exactly like everyone else. Watching him for some sort of response, Kon stepped back to let him in.
