You are a very frisky and sharp man who is afraid of little and you have been captured by the pirates of Blackbeard. (Well done ^^)

Van Augur was left to follow you because he is very courageous in this regard and he can not be distracted by anything for quite a long time and you became curious, well, if you can defeat him in a simple hand-to-hand combat, then you can probably escape. You offered him this option: If you defeat him in hand-to-hand combat (without any weapons), then he lets you go. He also became curious about what this could lead to, so he agreed to this

When you realized during the fight that you were going to lose, you quickly went to the edge of the deck and said, "I won't give up alive," and you just jumped into the water. He provided for this, and therefore he teleported you back on board literally a second before you met the water. You didn't compete with him anymore.
