Remember when Hazel meets Gus for the first time?
And Gus is wearing this gray T-shirt that says Bulldogs?
The one he wears when he tells Hazel he thinks she’s beautiful.
And then they hang out for the first time and become friends.
He even wears it again in the movie.
Well, look at the T-shirt SHE’S WEARING when her parents come in to tell her that Gus has died.
Yes, the SAME T-SHIRT GUS WORE WHEN THEY FIRST MET.
