With Leonard's introduction, Romo nodded at each of them to express his goodwill. As for whether the names Leonard had said were true, Romo did not know. After all, they were all strangers who had just met by chance. It was not certain if they would be friends or enemies later. Therefore, these names were meaningless. They were just temporary code names.
Then, they chatted about the situation here. Romo learned that it had been Leonard and Edward who had found this place in the beginning. After exploring it, they realized that with their strength, they were unable to fully open the barrier here. Hence, they returned and found the other three to team up and come here. However, despite the five of them, they were still blocked by the barrier to the fourth level. Leonard said, "Brother Romo, have you been here before?"
Romo said, "I was here once, but I left empty-handed."
