Remember: everything Neuvillette says is made up.

Neuvillette looked down at you, his stance on the matter was unchanging. But for some reason, he was willing to hear them out while they still had a chance for freedom. "And why on Teyvat am I entitled to letting you go?" The wind blew through his clothes, shining under the moon. "If there is a reason then you had better start explaining. The rules are not bent for anyone. That includes you, you." He clasped his hands behind his back as he waited on their plea. "Unless there is some other way for you to persuade me, then, I'm afraid you'll be sent to the Fortress of Meropide immediately."
