Xigger has a stronger divine sense so he should have sensed them before Ragnarok did. But he is pretending not to know about them. That means that he is toying with Ragnarok. Ragnarok decided then that he won't be fooled.
Xigger maintained his look of innocence and refused to admit it. He even pleaded with Ragnarok, "Please trust me, I don't know anything about this."
Ragnarok didn't argue anymore. He stayed silent and contemplated his options. He can't run and he is weak so he is at the mercy of Xigger. The only thing he can do is commit suicide.
He said to cheer himself up. "It wouldn't be so bad. I won't be the first clone to fail their mission. Legion-7 didn't even reincarnate properly and he was enslaved. At least I reincarnated into the race that I was supposed to reincarnate in. I will die but I can be reincarnated again. Legion-7 can't since he is still a slave. So my situation is not the worst one."
