Pepper’s visits alter Carney’s perception of his neighborhood, illuminating hotbeds of criminal activity in out-of-the-way places.

That Carney used Big Mike’s (undoubtedly stolen) cash to lease his furniture store means that he owes a portion of his success to criminal enterprise. Knowing how conflicted Carney feels about his father’s legacy, it is safe to assume this detail of his shop’s origins irks him and makes him doubt his own integrity.
