What are Taylor Swift's 'Patient Zero' lyrics about?

In 'Patient Zero', Taylor offers to console someone who's dating her ex. She sings: If you wanna party with somebody who might know / About the devil on his shoulder under his halo / When the toxins take their hold, you'd rather die than let it go / But if you’re sick of him, I got you, I was patient zero.

In using the term 'Patient Zero', Taylor is implying that she was the first to experience her ex's terrible ways and his habits are so harmful that they metaphorically lead you to wanting to be hospitalised to recover from the damage.

In a statement about the song, Taylor said: "The story behind me writing the song 'Patient Zero' is that I was hanging out with a bunch of friends, and one of my friends told us that she had been reached out to by the new girlfriend of an ex of hers, asking for guidance on if she had had the same experiences with this guy."

She continued: "Everyone in our group just immediately started saying like, 'Oh, I've been through that too', and telling the stories of when this kind of reach out had happened for them."

Taylor is yet to say who inspired the song but one huge theory is taking ground. A fan tweeted: "ngl I think patient zero isn’t about one person, I think she references a bunch of her previous relationships!!!"

In the theory, they've pointed out that there could be references to Joe Jonas, Matty Healy, Joe Alwyn, Jake Gyllenhaal, Harry Styles and John Mayer.

For example, fans think the first verse may be a reference to Sophie Turner and Joe Jonas. Taylor sings: I've gotta be honest, I've been expecting your call / No, it’s not a bad time at all. Taylor and Sophie famously went for dinner amid Sophie and Joe's divorce. However, the lyrics appear to reference more of Taylor's relationships.

I bet he burst into your life like fireworks could be a John Mayer and Katy Perry reference. "fireworks" lyrically calls back to both Taylor's song 'Dear John' and Katy Perry's own song 'Fireworks. Katy famously dated after Taylor.

People also think And when you saw another woman coming out of his place / I bet he kissed the rain off your face could be a reference to Harry Styles in 'Is It Over Now?'.

Taylor then appears to tap into other past relationships like Jake Gyllenhaal the bridge. I know he charmed your family and friends / And you thought it’s 'cause he loves you / But it’s 'cause he loves how everybody else loves him is akin to Taylor singing You who charmed my dad with self-effacing jokes in 'All Too Well (10 Minute Version)'.

Some people believe I know it seems like he shines so bright / But he's bathing in your reflected light / On a free solo social climb is a reference to Joe Alwyn gaining fame through his relationship with Taylor.

And finally, Someone who knows she's more than just the chase could be a dig at Matty Healy losing interest in her when they actually dated.

Who do you think Taylor's 'Patient Zero' lyrics are about?

Taylor Swift - 'Patient Zero' lyrics

CHORUS
If you wanna party with somebody who might know
About the devil on his shoulder under his halo
When the toxins take their hold, you'd rather die than let it go
But if you’re sick of him, I got you, I was patient zero

Taylor Swift - 'Patient Zero' lyrics

VERSE 1
I've gotta be honest, I've been expecting your call
No, it’s not a bad time at all
I heard somebody saying there's trouble in paradise
And my lips are sealed tight now

PRE-CHORUS
It's not for me to tell
Someone else what to do

CHORUS
But if you wanna party with somebody who might know
About the devil on his shoulder under his halo
When the toxins take their hold, you'd rather die than let it go
But if you're sick of him, I got you, I was patient zero

VERSE 2
I bet he burst into your life like fireworks
I bet he even said "I love you" first
And when you saw another woman coming out of his place
I bet he kissed the rain off your face

PRE-CHORUS
Now he seems bored by you
And you don't know what to do

CHORUS
But if you wanna party with somebody who might know
About the devil on his shoulder under his halo
When the toxins take their hold, you'd rather die than let it go
But if you're sick of him, I got you, I was patient zero (I was patient)
I was patient zero

BRIDGE
So let’s get into it
I know he charmed your family and friends
And you thought it’s 'cause he loves you
But it’s 'cause he loves how everybody else loves him (Uh-huh)
I know it seems like he shines so bright
But he's bathing in your reflected light
On a free solo social climb (Uh-huh)
Take it from somebody who lost his games but won the race
Take it from someone who said all of this to his face
Someone who knows she's more than just the chase
Someone who had him and walked away
And so

CHORUS
If you wanna party with somebody who might know
About the devil on his shoulder under his halo
When the toxins take their hold, you’d rather die than let it go
But if you're sick of him, I got you, I was patient zero

OUTRO
So if you wanna kick it, then I'm with it, I've been there
Felt the reeling, done the healing, said the curses and prayers
When the fever turns a dreamer into a pathetic ghost
If he's killing you, I see you
I was patient zero, oh
