Excellent episode. All the pieces are in place. Barnabas has managed to dodge the bullet once again, since no one believes Jenny could have seen what she saw.
Quentin was being a bit too docile about being bait with his back to the door. But then we see the garrotte.
Poor Beth is being torn in half over her feelings for Quentin and her loyalty to Jenny. Admitting to Quentin (after everything she did to convince him NOT to harm Jenny) that she wishes something would happen to Jenny, that he would have no wife --and poor Jenny being in the wrong place at the right time to hear this. One does wonder if hearing those feelings from Beth, the feeling that she's been betrayed by even Beth, is what sets Jenny off this time.
And here Beth is spilling all these feelings of uncertainty and guilt, and Quentin's response is "you have ME'.
Of course there's always the REAL question -- what the HECK was a knife like that doing in what looks like a bread basket in Beth's bedroom?
