Gregory knew for once that Alita lied to him and the way she was glowing; it didn't take a fool to not see that the other had eaten some meat.
He couldn't ask a grandmaster why she was cheating on his sister; his sister had stolen Alita from others from the beginning. And Gregory had seen a lot of men having many women so seeing this wasn't that shocking anymore.
No one stopped them from leaving and Gregory was very relieved. In his head he thought that Alita sold herself to keep them both safe and somehow apart from feeling sorry for his sister, he was happy that it wasn't him who sacrificed himself.
When they reached country G, he was happy to be home again and he didn't make things difficult for Alita and let her go to the hotel. They would meet and talk tomorrow so he didn't mind.
When Gregory arrived home, he met his elders and narrated the things that had happened. He didn't even leave out what happened on the day of departure.
