There was a reason Lex had been putting off going to the resort. He had a quest with a time limit hanging over him, yet repeatedly he pushed back going to the resort. It wasn't because Lex was averse to the idea, but because his intuition had been warning him to keep a distance from angels.
The warning wasn't a subtle reminder either, as if letting him know that if he met the angels he'd face another inconvenient quest like the main character from a video game. Rather, this was like common sense telling a mortal not to walk onto the site of an impending nuclear explosion.
Even if he didn't consciously pay attention to it, the feeling was there, in the back of his mind, subtly nudging him away from it. It was only when he was consciously faced with two decisions, both heavily involving angels, that he finally realized that he had been subconsciously avoiding both of them.
