In the epilogue when Harry is telling Albus Severus about being sorted.

Harry: "Albus Severus, you were named for two headmasters of Hogwarts. One of them was a Slytherin and he was probably the bravest man I ever knew."


I just loved that part of the book. Really shows how Harry forgave Snape and how he wasnt as prejudice towards Slytherin house as before. Hopefully litte Albus did end up in Slytherin.
