Where is Elena's Studio? Why was Grace walking near there?
They kept calling it 'apartment', by which I assumed it was an apartment she had made her art studio - tho it looked more like a shopfront. They lived in a less than great part of the city, and her son walked from their home to the studio to discover her murdered.
Grace lives in a much nicer part of the city obviously, so why is she taking her strolls in the same area as Elena's apartment/studio?
I'm not familiar with the geography of NYC but it seemed like they wouldn't be in anywhere near the same neighborhood.
