chocolatetea I think you've nailed it. The cow eyes at Nick wasn't a stupid oversight on the part of the directors, it was a clever dig at serena that she has something over her. At that point June was still firey and angry and fighting back.
I think she has now decided the best thing for her and everyone else is for her to try and give up the fight. They have boarded up the inside of the wardrobe. I think losing that message was the last straw for her spirit. I wonder what/who will shake her back to herself?!
I have watched every episode 2 or 3 times this series (season 1 I binged watched and don't remember the detail so much) and I see/hear new things every time I watch an episode again.
I didn't know the songs were a hidden message, how interesting!
