The pairing of Ron and Romilda is an inspired choice, especially in light of what happened in canon sixth year. That was a good "straight-talk" session with Albus, something he's needed for a long time. The last line was a classic and I really doubt that he's going to teach them as a whole class of people but he will ahve success with some individuals. It should be educational to see if any pure-blood supporter/fanaticx do manage to truly learn that actions have consequences and that they are not immune.
