Living in Kirkwall, Fenris has seen his fair share of people who were more than a little off for one reason or another. The man in front of him rather seems to run in the same vein, so Fenris just watches him closely. There's a minute flinch at the sudden raised voice, but his expression remains the same.

At least until that last comment, at which point he clears his throat and glances away a moment. He doesn't appear especially bothered by the flirtation, but in the moment he isn't sure what to do with it, so he just...skips over it.

"That would explain a few things," he mutters blankly. Mainly the acute aches in various places.

He looks back at Klaus. "Were they carrying gauntlets and a great sword by any chance?"
