TVLINE | When did you decide that Dan would be Gossip Girl?
Sure their friendship was complicated, but he was loyal to everyone in his life. He never settled and therefore didn’t want his friends to settle either. He was so proper and raised so well, despite his parents’ faults.
Seriously, he was probably the most loyal of the crew, which says a LOT. A guy who wanted to find love, what’s not to like about that? Nate was wealthy sure, but he wanted to be more than just a rich kid who had a famous family. Unlike a lot of the jerk characters on the series, Nate was a serious gentleman who cared about other people and how they should be treated.
It was unclear if knowing Gossip Girl’s identity was something fans would want.
Maybe it was more fun for everyone to know who Gossip Girl was and be able to speculate and come up with your own ideas.
