Right before her death, she remembers herself making one last wish.

Another chance.

The arrows have frozen in mid-air – Snow screaming Stop! – and she was still alive.

Show them you can change, Daddy said, and she's failed – she tried to kill Snow again, because it was too tempting to resist.

She's used to be blamed for her crimes.
She's not used to carry the guilt for a crime she hasn't committed.

Archie.

Henry – and Daddy, have always believed in her, and she has failed them both.

Her son breaks down, embraces Emma, and she watches – nobody believes in her anymore.
