@Adela *SPOILERS* I'm not sure how right I am, but I know that Ilay basically becomes a terrorist to get Taeui out of there. As for the fight between Ilay and Xinlu, Ilay basically sticks his finger into Xinlu's eye and blinds him. That's as far as I know.
Ilay comes to save Tay by blowing up the villa. Then before Ilay can get to Tay, Xinlu takes Tay's brother forcing Tay to go with Xinlu instead of Ilay (coz Tay doesn't want Xinlu to do something bad to his brother). Ilay thinks Tay wanted to leave him, not knowing Tay didn't have a choice. Xinlu takes both brothers to a hotel. In the morning Jay goes to The UNHDRO so he can be safe, and Tay goes to find Ilay, though others recommend him not to go. He's at the bus stop waiting for a taxi to the airport when Ilay shows up. He's like super mad and stuffs a glove in Tay's mouth so he can't even explain what happened. He takes him away and gr*pes him. I don't remember the very very end. I hope I explained it okay.
