Gossip Girl: Diana's Big Secret is Revealed! She is [Spoiler]
Gossip Girl delivered up a plot twist in this week's episode, although rumblings on the internet indicate that some fans predicted the outcome. Chuck has been searching for his mother after learning that his uncle didn't give the blood to save his life after his car accident. But his private investigator revealed that the woman he believed to be his mother - Elizabeth - wasn't in New York around the time of his accident.
All of Chuck's searching has proven fruitless, but it only took Serena an episode to figure out the truth: Diana Payne (guest star Elizabeth Hurley) is actually Chuck's mother! Apparently, the original Gossip Girl knew the truth about Chuck's maternity and had used the secret to blackmail Diana. After Serena refused to give Gossip Girl the new password to her site, GG turned to Diana, demanding that she make Serena give up the gossip throne.
Naturally, Serena was slightly freaked out that someone knew the truth about her secret side job, so she decided to do a little digging on Diana. After overhearing Diana mention being at the hospital after Chuck's accident, she approached a nurse with Diana's photo. Later, she confronted Diana at Blair and Dan's coming out party. But Lola had been suspicious about Serena's side job for most of the episode and she decided to live stream the private conversation between Diana and Serena, at the end of which Diana did confess that she was Chuck's mother.
Chuck was understandably upset when he learned the truth, considering Diana had kept this news from him (as well as "banging [his] best friend"). After storming off, Lola confronted Serena about being Gossip Girl, but agreed to keep her cousin's secret. She has, however, lost Nate, or so it would seem. He couldn't forgive her for airing Chuck's family secrets online.
At the end of the episode, Diana went to visit Chuck, who agreed to speak to her. She said that she had had an affair with Bart Bass and couldn't resist him. After Chuck was born, she admitted she was unfit to raise a child, so she gave him to Bart and Elizabeth to raise. A few years later, after Elizabeth's "death", she returned, but she and Bart decided not to bring her into their son's life. Diana claimed that she did want to see Chuck and has spent this time watching over Chuck from afar. In the end, Diana left the choice about whether they'll be a family up to Chuck.
As an added surprise, Diana got one last text message from Gossip Girl at the end of the episode. It ominously said "we both know [Chuck's true maternity was] not the secret I was talking about".
