Ehren has a lair within the shark that is so cool that Batman is now consumed with jealousy, and is now attempting entry by confusing the guard-shark by interpretive lightsaber dancing in order to fool them all into thinking he has furies, but Batman is no Tavi, sir. No Tavi! Therefore, Ehren wins.
Whether or not Ehren still required pants for this plan is up to your individual opinions.
