Bellatrix Black failed to kill her first time, but compared to Amors Diggory, her magic is weaker after all.
But why can't she kill him after three years? !
Amors Diggory is not unlucky. He encountered a violent incident on the eve of his engagement, and then ended up on an unknown island for no reason.
Being chased by a crazy woman for 3 years should be enough! ?
