Well, Petofi didn't really let Beth in on what he was planning to do with Quentin. What I don't understand is why she bought into Quentofi when he couldn't answer one question about Jamison. That should have made her a little suspicious.
And certainly Angelique should have thought something was up when 'Quentin' is now ready, willing, and able to marry her. Did she really think he'd get over Amanda that fast? (Then again, this IS Amanda we're talking about so I guess Angelique can be forgiven here).
Poor Quentin. Just when he finally gets someone to believe him, Julia, she disappears before his eyes. It appears there is no help or hope for him. What's a guy to do?
