Blood Status Importance
I was just wondering in DH what the importance of having blood status would be. They say they need to have it before going to Hogwarts, but what do they need it for? Are they not allowed to go if they are muggle-borns? Or will they just be tortured? How do they check at the gate? Do they have a person looming over, asking what their status is before they get on the train? How do they let the muggle-borns know that they need to be taken in for questioning? How do they find the right muggle-born? This information would all be helpful.
Thanks in advance!
