I love their scenes, I wonder if she'll ever tell S the truth about what happened with Chuck? I was kinda sad when she told nate specifically not to tell serena about what happened. I have a feeling they'll just glaze over it and have serena act like she knows even though no one ever told her. Like how Blair just knew (in 2x25) that chuck told nate he was in love with blair in season 1. No one ever mentioned it.
I guess it was a problem. Serena is busy, but Blair is too - she spends most of her time with Chuck and her new mignons so IDK. They've been through so much together, yet they can't communicate. It's sad.
