"We can find you again."
Adam saw the subtle threat that William said to him in those words.
Instead of being angry or concerned at those words instead he was actually happy to hear them. Not because they were meant to demean but because the kid in front could actually give the most decent threats.
Most of all he was happy that he was actually trusted enough to be given the sword and also to keep it hidden away from anyone's prying eyes.
He didn't care about William or his entourage finding him because both knew that it would be quite troublesome to find him if he truly tried to hide. The only reason they were even able to find him this time was because he wanted them to.
So the blatant trust was the main thing for Adam. In his life most didn't trust him because of his background. No matter how strong he had become the only thing he garnered from people were there jealousy and nothing else.
