It was inappropriate for Auretin and Ian to enter Gu Mengmeng's house, so Lea set up a huge pot outside of the house and told them everything that happened after Gu Mengmeng left while cooking.
The situation was a mess that time and it would be wrong to say Ian's decision was incorrect. After all, the entire Saint Nazaire had been controlled. Even as the Messenger of the Beast Deity, Gu Mengmeng was like a clam that had lost its shell in that situation, it was too dangerous. Compared to remaining in the unknown danger, going to the tribe of the previous Messenger and ask for protection was the best choice. Even if Cole had any other motives, the identity of the Messenger was made known to the public and Cole had to protect Gu Mengmeng no matter what.
