Merlin is gone but will he remember what happened??

Merlin's younger sister turns up what is going to happen?

Hermione Granger, Gryffindor's Good Girl, Head Girl, Cleverest Witch of her Age, Nice to even the lowest of the low, Charity starter, Best Friend, Savior of the World, Best Auror in the making...Wanted for MURDER. Now, how does that even make sense? Draco wants to know...don't you?
