So when Ilay is talking to his brother, he's sort of acting tough or putting on his act of violence. The reason we know he's acting is because when he realizes that Tay heard him, he has a reaction. He cares about what Tay thinks, even if he's in denial of his feelings. Because of he didn't care about Tay, he would not have had ANY reaction to seeing Tay behind the door. Even the brother is surprised to see Ilay have a reaction. Imagine a cold-blooded killer caring about a what seemingly "nobody" guy thought of him.
I saw some comments about ilay reaction if tay heard anything, but what does that reaction mean , I’m lowkey slow, I barely notice the small details .
