Lex, with his weary mind, was stunned by what had just happened. His eyes followed the visage of Vera walking away as he tried to understand what the point of that was. It was only a couple of minutes later that he came up with an answer.
Vera was an oracle herself. That not only provided her with great insight into the profession, it also guided her actions. She had once appeared quite timely to help him assess John's abilities before hiring him. As such, there was no reason to believe that her current actions, while bizarre, weren't guided by prophecy as well.
Lex groaned. His headache was really affecting him, and his exhausted state made it hard to even think. It had been much too long since he was in such a poor condition.
He reached for a plate of french fries and snacked on them as he continued to challenge his brain.
