Many Eyes also said to Star Divination, "Come back. We have to fight. The thief is clearly determined to get rid of us."
He said that to her because he was sure that the thief's promise not to kill him was a lie. In fact, he was sure that the thief would try to kill him next.
The thief's promise not to kill him had convinced him that he had a 100% of being pursued after the deceiver dies. Since he was next in line to die, it became a good idea to fight with the deceiver for a chance of survival.
What would be better is if Star Divination also joined in the fight. Unfortunately for him, she was not willing to risk her life like that.
After she heard his words urging her to fight, she laughed and said, "It seems you're screwed. But that's a good thing for me, though. So why would I jeopardize my chances of surviving by coming back to fight?"
