Fans hoped Emmy Rossum would return as big sis Fiona for the series finale â hey, you canât always get what you want â but this was as good of a substitute that viewers could expect.
As Frank wandered Chicago for the last time, his storyline paid homage to the eldest sibling. This included pit stops at Patsyâs Pies (shuttered), where Fiona had been a manager once upon a time ago, and the church where she was supposed to marry Sean (Dermot Mulroney) in Season 6. Later on, Frank mistakes one of the nurses for Fiona, remarking how beautiful she is as he lays dying in the hospital. That might feel like a throwaway nod to Rossumâs character, but itâs actually quite sincere and poignant once you know that the actress playing Frankâs nurse is William H. Macyâs own daughter, Sophia Macy.
