One foggy day, a 15 year-old girl showed up in Hogwarts. After 5 minutes lucubrating over her head, the Sorting Hat finally shouted: Ravenclaw! She was brilliant at many things, such as reading, writing, and watching TV series like there's no tomorrow. That's probably the reason why she was reaped in the Half-Blood Camp to join Athena's army and fought in the 73 th Hunger Games using a sonic screwdriver as a weapon. The raggedy Doctor took her to his Tardis, whose force field hided her Divergence from Jeanine's sight...
Ah, probably didn't mention... This girl we were talking about... Yeah, that's me.
Have a nice day!
