Who is Patient Zero? Taylor Swift fans decipher references to her exes on 4 new songs

The arrival of new Taylor Swift music automatically sends fans on a quest to find the hidden meanings in her lyrics – and the release of four new songs on The Life of a Showgirl: The Encore is no different.

The extended version of 2025’s The Life of a Showgirl includes four singles, “Patient Zero,” “Pink Clouding,” “Babylon,” and “Cleveland,” each of them filled with cryptic lyrics and Easter egg references, which is trademark Swift.

The singer revealed all four songs were written on a celebratory trip to Sweden with her The Life Of A Showgirl co-creators, Max Martin and Shellback. “Really, we just wanted to reflect and take in how grateful we were for the moment we were in, but there was a studio there and we did what we do when we feel anything at all: We wrote more songs,” she said.

From calling out her haters to criticizing a toxic ex and apologizing to another ex, there is a lot for Swifties to pore over. Below, we unpack what the lyrics could mean…

‘Patient Zero’

“Patient Zero” tells the story of a woman reflecting on her relationship with a toxic ex, and Swift is thought to be the “patient zero” in the scenario – possibly the first person to be subjected to the man’s pattern of behavior.

The broad term patient zero typically refers to the first individual identified with a disease or an illness in a new outbreak.

In the song, she describes a man who “burst into your life like fireworks” before revealing his true colors. She describes that the man had “the devil on his shoulder under his halo” and that he used her for social climbing.

She also appears to be addressing a woman now dating that ex-boyfriend, as she sings: “It’s not for me to tell someone else what to do / But if you’re sick of him / I got you / I was patient zero.”

“I know it seems like he shines so bright / But he’s bathing in your reflected light / On a free solo social climb,” she sings, also alluding to infidelity, when she sings: “And when you saw another woman coming out of his place / I bet he kissed the rain off your face.”

‘Cleveland!’

“Cleveland!” is clearly about her husband, the Kansas City Chiefs Tight End Travis Kelce, and how he appreciates the things about her that other people publicly criticize.

The title is a reference to Kelce’s hometown: Cleveland Heights, Ohio.

At the beginning of the song, Swift recaps criticisms she has received from online trolls about her dancing, appearance and clothes.

“But my baby likes what he likes, oh-woah, oh-oh / He already took me to Cleveland / And showed me The Heights, so hate all you like / This is the love of my life, hey, hey, hey,” she sings.

She continues: “The taste of me is acquired, but it’s his favorite dish… He likes what he likes, what he likes, and he likes me.”

Out of the four new releases, the song has been the most poorly received by fans.

“I’m sorry Cleveland! is laughably her worst song yet. How did the same woman who churned out evermore just 6 years ago manage to decline to this,” said one fan in a post with 1,300 retweets and 16,000 likes.

“Debating on getting a new phone just so I have a phone that’s never listened to Cleveland! bc wtf was that,” said one fan, as another replied: “Can’t buy new ears.”

One fan added: “I am very much a lover of fun songs, but this one really doesn’t do it for me. Something about it is really grating, especially the bridge. I do love the sentiment and the line ‘This is the love of my life!’ though.”

Others have been more positive. “Cleveland! is as Showgirl as it gets,” said one fan. “A figure abused with misogynistic insults, haunted by sensationalized narratives, discarded as shallow, her complexity erased. It both pokes fun at that while expressing how liberating it is to find a partner who appreciates you as a whole.”

“I aggressively love Cleveland!” said another fan. “I’m saying it now before y’all tell me I’m supposed to hate it and it’s objectively bad. Leave me alone. I love it.”

‘Pink Clouding’

“Pink Clouding” is thought to be about an ex that Swift let down or met at the wrong time. The term pink clouding, sometimes called Pink Cloud Syndrome, is a period of intense optimism or euphoria that can occur early in addiction recovery before the realities set back in.

The expression can also refer to a temporary euphoria after something bad happens.

In the chorus, she sings, “‘Cause I was pink clouding from the thrill of it (Pink) / Skydiving as you wrapped your arms around my body / Gray rocking where the arrow hit (Gray) / Years later, I still wonder how to tell you sorry / I didn’t want to let you down (Pink cloud, pink cloud) / So I left you up there on a pink cloud (Pink, pink cloud).”

Swift seems to apologize to this ex when she sings, “I hope you realized my kind of trouble wasn’t worth it / And the way I treated you, you never deserved it / And I swear to God, to this day / I wake up scared that I left scars on a good person.”

At the end of the song, Swift says she hopes the man “landed safely on the ground” and “I hope you’re so happy now.”

Fans think that this song must be about an ex-boyfriend who she still views highly, which could be Harry Styles, who she dated from 2012 to 2013, or Tom Hiddleston, who she dated in 2016.

‘Babylon’

“Babylon” tells the story of a guy leaving a small town and his girlfriend behind for something bigger, and then regretting it.

The Hanging Gardens of Babylon are one of the Seven Wonders of the Ancient World, but scientists have debated whether they actually existed.

Swift first referenced the Gardens of Babylon on her song “cowboy like me” from the 2020 album evermore. She described an elusive romance: “Now you hang from my lips / Like the Gardens of Babylon.“

In the new song, she sings: “Then that melody is all you want/ You never knew that it was Babylon/ ‘Til it was gone.”

Some fans have said that the song describes how nostalgia can be painful. One fan wrote on X that Swift’s “use of detail is masterful,” writing: “‘Babylon’ captures her philosophy of life so beautifully. Nostalgia is a weapon that hurts you and everyone who’s rooting to grow with you, in your light. But you have to remember your roots to move through the world with lightness and conviction.”

Another fan hypothesized that the song is about someone never being satisfied by what they’ve got, and constantly chasing the next objective until they realize what they missed out on.

“[They] realize that what they had was the best thing but now she’s moved on and is happy and now you just have to sit with knowing that you could’ve had it all but f***ed it up,” wrote @SwiftieESPN on X. “And also it’s a bop and I’m obsessed.”

“Babylon is written to all the men who think you look better in the rearview,” said another.

Some fans have concluded that “Babylon” and “Patient Zero” are the favorites of the new four songs.

One said on X: “I am obsessed with Babylon as a nostalgic in a painful way girlie.”
