They did not attack Arthur, or did anything at all. The same youth who was saying those bad words to them said, "I will remember you face." Then left.
Arthur was not concerned with it at all. Even though he was pretending to be someone weaker, there was no chance he would lose to these people who barely had any actual combat in their lives.
He got his water and then returned to the remote place they built their temporary shelter. There, Lucas had returned with a few rabbits.
"I'll return to get a bigger one." Lucas said.
Anyone could tell it had been tiring for him to hunt in that area, as it had many magical beasts.
"Don't. I will get a few more for us, just rest near the campfire." Arthur said.
Lucas nodded and did as he was told. Liz had already made a fire for them, so he wanted to get some rest, but did not want to say it aloud. Arthur dropped the basket with water near them and left.
