The appearance of Nina's partners was what Lea had wanted.
Warming up his wrists, Lea said, "It is equivalent to ignoring Saint Nazaire's tribe rules for you to trespass others' boundaries. As the witch doctor, I cannot pretend that I did not see it."
Nina's partners looked at each other, Lea's words sounded wrong, but it also seemed like everything made sense. It was impossible for their brains to think of a rebuttal to Lea. Moreover, them trespassing boundaries was a fact, there was nowhere they could start arguing for this. So one of Nina's partners kneeled down by Lea's foot in a submissive way, which was a position to show a beast's obedience. After all, they do not dare to go against Lea.
"We just wanted to bring Nina back and we had no intention of violating Sandy's boundary. Lea… Oh, I mean, Witch Doctor, please forgive us."
