Death's Hand In Mine

*Takes place slightly before the occurrences of episode 1 and then progresses sort of similarly in relation to the seriesCenturies after their bitter parting, Cass, now a powerful witch, finally tracks down her former mentor, Agatha Harkness, in the quaint suburban town of Westview. However, instead of the cunning and formidable sorceress she once knew, Cass finds a strange version of Agatha. Stripped of her memories and powers by a spell cast by the Scarlet Witch, Agatha lives a bizarre, mundane life as a detective. Then it's mostly plot compliant but with this different character and also a happy ending.PS: English is not my first language so please, feel free to point out any mistakes
