17 details you might have missed on season 1 of HBO Max's 'Gossip Girl,' so far

On the continuation series, a teacher at Constance Billard named Kate Keller (played by former-blogger-turned-actress Tavi Gevinson) is seen on a train passing through Brooklyn.

On the original show, the premiere opened with Serena van der Woodsen (Blake Lively) on a train arriving at Grand Central Station.

The context for the two moments differs, though. Kate is en route to Constance Billard for the first day of the new school year.

On the original show, Serena made a return to NYC after attending a boarding school.

Both characters are seen wearing striped shirts, tan jackets, and printed scarves around their necks.

The trophies belong to Julien Calloway's (Jordan Alexander) dad named Davis, who works in the music industry.

The decor of Zoya's room also indicates that she lives a less opulent life than the other characters.

The pile includes Morrison's "The Bluest Eye," Baldwin's "Notes on a Native Son," and a literary magazine called the Paris Review.

On the new show, it's technically a scarf that Zoya wears on her head. Julien's friend Monet de Haan (Savannah Lee Smith) scoffs at Zoya's fashion choice later on in the episode, implying that headbands are no longer as fashionable as they used to be.

This is revealed when viewers see Julien ordering a metallic dress from Alice + Olivia online. She lists Zoya's address as the shipping address but has the purchase billed to herself at 400 Duane St., Penthouse 55, New York, NY 10013.

Kate's mention of the original GG character Nate (Chace Crawford) suggests that he became a notable figure in the years since he was last seen on the prior show.

Although, a teacher named Rebecca reminds Kate that Nate didn't have a squeaky clean image when he was a student at St. Jude's.

"People thought it was me, but it was actually one of my classmates, Dan Humphrey," she says as she explains to her colleagues how GG kept the students in line and made them accountable for their actions.

It's unclear what Dan (Penn Badgley) has been up to since he came clean about his identity on the finale of the original series. But Kate refers to him as a "novelist," which means he's still a writer.

The new show is set in 2021, nine years after the blog went dark. The series also takes place post-pandemic.

As Kate scrolls through the GG blog, she says: "This Chuck and Blair thing is out of control. Definitely pre-cancel culture."

This is a nod to one of the most problematic and polarizing couples on the original show.

The other teachers also mention far-fetched, unrealistic plots from the original series, like Blair being the Princess of Monaco for six months or high-school senior Dan getting published in the New Yorker.

This moment happens when Julien and Zoya meet in the bathroom and reveal the matching tattoos they got. Julien getting inked by a famous artist further highlights her wealth and social status.

The Met was a common spot for the characters of the original series to eat lunch and gossip about their peers.

The essays were published in 1996 and discuss the dynamics of women in affairs, friendships, and families. It could be a hint at what fans can expect from Audrey's storylines this season.

This is a nod to his character being environmentally and socially conscious. In the same episode, Julien calls him "guilty rich."

On the HBO show, the teachers read a post that says, "Spotted: Chuck Bass losing something no one knew he had. His heart."

The same phrase was uttered by GG on season one, episode 10 ("Hi, Society") when Chuck became jealous after seeing Blair and Nate kissing.
