"Now, if you don't mind, I would like to ask you about the fight you had with the boss last night," Yahiko said. "I have some predictions about the creature you faced, but I need to confirm it."
Ryan also wanted to learn more about the creatures in the other dungeons, so talking now would help him in the short term. While Ryan still wanted to work alone, he didn't need to work against Yahiko.
"Titania, huh," Yahiko said. "As expected, we didn't help you last night because Oberon, the king of fairies, left his dungeon and tried to interfere in your fight. Just as I mentioned before, I held him back and his army in the South."
"You failed at killing him?" Ryan asked.
