During Blair's party, Vanessa catches Nate with Catherine right before a city-wide blackout (that traps Serena and Dan in an elevator).

It also ranked #1 in adults 18-34 for the night, beating shows like Two and a Half Men and The Big Bang Theory.

[4] Michelle Graham, from Film School Rejects, said "Catherine’s comments on her need for Nate and how Blair’s relationship with Lord Marcus might be missing one thing is an interesting parallel", and also said that even though "it was nice to see Vanessa again", "she did come off very whiny and a tad annoying".

She also said that "Jenny’s sudden rise from intern to confidante of the designer felt incredibly contrived", and that the scene where Blair make-out with Chuck knowing that it's him, not Marcus, makes "no-sense".

[6] Kona Gallagher, from Television Blend, had said that she felt "silly" that Catherine was jealous of Nate and Vanessa's relationship, because in the end she's a married woman.

She was confused and angry over the reason that lead to Serena and Dan's break-up by saying that it was such a "clichéd class war nonsense".

[7] Amber Charleville, from Firefox News, said that Dan's reason to break-up with Serena "sounds more like bitter jealousy than righteous indignation" than something else, and that the episode overall "ties up a lot of loose ends, but makes others fray unbecomingly".
