A few thoughts / observations from this episode:
I wholeheartedly agree with others who have stated Liza appears to be regressing to her 26 year old assistant self. It's almost as if she's going through a mid-life crisis, now that she's moved up to a position of authority / responsibility. Now that she's with Charles, and Josh has accepted this fact she's pinning for Josh. Make a damn decision Liza, this isn't cute anymore.
I'm not sure who's worse, Liza or Kelsey: Liza for showing Charles' book to Kelsey as a possible pitch, or Kelsey for not honoring Liza's request of not mentioning it to Charles without giving her thoughts to Liza. It wasn't Liza's damn business anyway...
Speaking of Kelsey, I am probably in the minority but I am not buying Kelsey as the publisher, not at all.
And for all that is Holy - HOW does Diana STILL NOT KNOW about Liza's age?!
Speaking of Diana - I am THRILLED for her and Enzo, but she has to let Charles go!
