Aragorn believed he was a major threat to you and your safety.

you used to live a safe, perfectly ordinary life, but now you were standing in an open field with a blade in your hand that he had taught you how to use.

this wasn’t normal.

you shouldn't have agreed — or rather, he shouldn't have agreed to take you with him. but he needed people, and unfortunately, you were one of the few who stepped forward.

the rest of the group split up, leaving you paired up with Aragorn.

"I'll put out the fire, and we need to get some sleep," he said, looking around. "there shouldn’t be any orcs in this area, but we must stay alert. go to sleep, and I'll keep watch."

you stubbornly stand your ground. "I want to practice a little more."

"you can do that in the morning." he walks over to you, draping his cloak over your shoulders, but as he gently reaches for the blade in your hand, you step back.

well, perhaps it was his own fault that, over time, you had picked up his personality traits as well.
