Yes Yes I know I know! I am talking about Hermione Granger the smartest witch of her age. Being a Death Eater. Remember how keen Hermione was to be friends with Ron and Harry? Why? Because Voldemort/ Quirrel asked her to! Why did Hermione take the blame about the troll?  Because Voldemort cant let him be expelled as he will be at his aunts house! It all makes perfect sense really But! Its Hermione! She always helped Harry! Well she was a Double Agent! In cursed Child she was eager to be Voldemort so she could  meet his child at last! Also wasnt she the clevest witch of her age but she couldnt do the patronus Charm? Neither can Death Eaters! She only can occasionally because even though she is evil when she didnt know Voldemort and was a normal girl those were her happy memories. But! I hear you all say shes a Gryffindor! Well so was Pettigrew! Really it all fits.
