*He shock ran through his body as he heard the Nord speak... Though now the familiar feeling he had seeing him was explained. How could he speak about that so openly?! Try to not let it get to you... Just ignore it... For now.*

It was obvious to even a not so skilled eye that the confession about the beast blood created a strong reaction in the Dunmer that he tried to fake away. 
He smiled softly, now very insecure... Seeming more nervous then before. 

"Oh! Ah... That's quite practical of course. I bet the... The beast is good hunter for such occasions. And a good protection against those leeches."
He tried to change the theme... "So you have an entire fort? Sounds quite nice. Not every guild can say that about itself, right?"

*His own words sparked an idea in the young Dunmer, though he was still unsure of it was a good one. He had no destination currently... And this guild could maybe needed a smith or craftsman to help with the fort... If it really was one and not one of the sad ruins he encountered along his way...
Plus that way he could stay close to the only person he currently knows that lives with the same... Condition... As he does...*

An expected reaction from someone not proud of the gift Hircine bestowed upon them and it confirmed his suspicion that he was Indeed talking to another moon born, another hunter of Hircine.

"The Fort has been there long before any of us have, we are merely picking up where the old dawnguard left off." He said as he dusted off his armor a bit.

*It was difficult for him, but he had a feeling that the Nord expected another answer from him. A confession maybe... Or at least him admitting that they share the beast blood? 
Still feeling unwell about his reaction and what he said, he decided at least try to "Compensate" The Nord.*

"If... If you are in need of a craftsman or a smith at the fort. I could help. I'm lacking a destination anyways... And I think currently I'm not really ready to traverse towards whitehelm or riverrun."
