What? How is this so far from the one I've read
Cuz as far as I know, Taeui went with Xinlu because he has Jaeui as a hostage and threatened to drug Jaeui if he does not come with him. Not only that, he also said that he will be treated as a prisoner nothing less because he does not have the luxury to treat him like Rahman does.
Another thing, he did not say that he wanted to take Taeui's eyes, yes he did in fact tried to kill Ilay but from what I remember he did not try to hurt Taeui.

For what I remember from the novel is that, something happens and Xhin Liu is able to break in, and Tae and his brother get into a helicopter with Xhin Liu, because Xhin Liu was going to tell Tae about the ghichale something,( sorry I don't know how to spell that word) , at the same time that this is happening, Ilay breaks in on his bike and sees that Tae is leaving, and he calls him to go with him, but Tae decides to leave with XL, so you can imagine the treason that Ilay felt...
After that XL tells T about the gichasomething, but T wants to go back with Ilay and if XL needs to take revenge from Ilay he can remove one of T's eyes. Then the shit happens
