Sirius Black! He was such a comfort character and a comedic relief in the movies that he was in. I grew to really love him )

Definitely the cloak, it my be very selfish but if I can be invisible then I'd be able to physically get anything I want and even know whatever i want to know.

I think I cried the most over Sirius Black. It was because he was such a father figure to Harry and over all just a comfort character. So when he was taken away in a blink of an eye there was a moment of shock followed by pool of tears being forms on the carpet under me haha
