Author's Note

'Nothing could ruin Cassandra's good mood, not even Emma Swan or her Storybrooke friends. Not when Cassandra was with Peter.

For he was hers and she was his.'

All heroes need a tragic backstory.
All stories need a knight in shining armour.

Cassandra had her troubled past. She had her knight in shining armour, if one could call him that. Unfortunately, in this tale, our protagonist is no heroine, and her saviour is no hero.
She has a thirst for revenge, and it just so happens to coincide with Peter Pan's plot for eternal youth. All she needs to do, to fulfil both their wishes, is help Pan kill the Truest Believer.
The fact that the Truest Believer was also the twin she had never met, placed no burden on her shoulders.
