They were at the gate of Yorktown city and so they were making sure that they don't get caught by the guards there and so they must be careful to make sure that they don't do anything that they will get caught and so they had to blend in so they don't get caught.
In the inner city. it is surrounding by the king's aura and so they had to be careful to hide their presence until they can enter into the Iron tower where all of the top rank fighters that travel to other places will come here to fight the strongest.
Behind them, a boy was looking at them with his eyes having a wolf symbol on his eyes and so he was hoping that he will see a powerful opponent so he just tails them. He was hoping that they will pass the gate without alerting anyone and he hoping that his hint is correct and they will entertain him.
