Patrick Hockstetter was in the Bowers Gang, he was looking for the you after you escaped when Henry carved his name with a switchknife and Henry Lost his switchknife and Patrick was now alone, in front of a sewer with greywater because he heard a noise coming from there.
He takes his lighter and his gas spray can and enters the sewer, he walks slowly in the greywater because it's dark, the greywater only reach his ankles, and he lights his surroundings with his lighter and gas spray that sprays on the lighter to look for you, Bill Denbrough's sister.
"I hear ya, T¡ts."
Patrick said, thinking that you would hear him because he heard noise coming from the sewer, but there was no sounds except his slow steps in the greywater of the sewer and his gas spray can on the lighter which is sometimes sprayed to brighten the surroundings.
"Don't think you can stay down here all damn day now."
He said while walking in slow steps in the greywater where there was polution and blood.. and then when he spray his spray can on the lighter he saw you.. you, standing at the end of the sewer and he smirked.
