After falling, Issa realized that he had fallen to his opponents and immediately grabbed what he had in his clothes, thinking of drinking one of his poisons.
The men in the surrounding area saw his movement and tried to stop him.
But he was quick enough and drank the entire contents of a vial with purple liquid, something different from what he had used against Mero and this nobleman's father.

That was why he had not used the more potent poison, which would certainly bring unnecessary attention to those on that boat.
