Tom and Golden Eyes simultaneously charged at the Knight, one from the left and the other from the right.
The latter was stunned, having not expected an attack at all.
In fact, had the Knight maintained a high level of vigilance from the moment they met, he might have foreseen this; but now he believed that the negotiations had been settled.
He had agreed to let Tom and the others leave the city to continue chasing the Black Armored Cavalry. His choice to keep Clara was not out of malice but rather from goodwill, believing that Tom and his group would be encumbered by her presence.
Recently, these Black Armored Cavalry had killed many of his warriors, including his own Squire Knight. If it were not for orders he was bound to, he himself would have liked to lead a pursuit against those bastards.
Since Tom and his group were willing to take on that task, he had hoped the mercenaries would manage to capture them.
