Baby Blues
Joey talks to Katherine (Heather Hess) outside the Chapel at Keefer Place and Carrall Street.
The trashy apartment building where Katherine lives is just up the street from here on Carrall Street...
...which can be seen in the background of the next scene (it has since been torn down)...
...where the officers move in on a man who they suspect is disposing of her unwanted baby. The building behind him still stands at 531 Carrall Street, and can be seen several other times in the show.
