Okay I just finished the episode over here in Australia.
OMG honestly one of my favourites from this season. I must admit the season had a slow start but I think it was building up to these last couple of episodes.
The acting was EPIC. What stood out to me most was Ed and Chase this episode. That scene at the bar where Nate said "he got to me." Chase honestly hit his peak. And the way Chuck responded. You could feel the tension and emotion. It was real. And when Chuck approached Lily with that look of complete and utter pain because of her betrayal. My heart broke for him. Ed really knows how to get a person emotionally involved with his character.
I love the direction they are going with when it comes to Chuck and Chair. I feel like everyone has misunderstood Chuck's need to prove himself and thought it was overrated. But the way he spoke to Blair and said stop lying to yourself. It's just one of those moments where you see the real torment inside Chuck. You can see every issue he has finally coming to the surface. His self-loathing issues, his trust issues, his abandonment issues. And Blair is the polar opposite of hating yourself, not being loyal and giving up on people. She's the perfect antidote to Chuck's pain. It's why they suit each other beautifully. It brings out this strong, loving, "partner-for-life" side to her. It brings out Chuck's vulnerable yet romantic side. I read a fanfic that described them as equals yet polar opposites. And that is exactly how they are portrayed in their final scene of the episode.
