Class followup

[alt_antonin]

I have seen several of our Gryffindor and Hufflepuff fifth-year students discussing the locking spell we covered in lecture on Wednesday, and several of our Slytherin and Ravenclaw students looking forward to the lesson on Friday (at which, yes, we will cover the same spell). I have not wished to intrude in your discussions: however, if you have any questions that were not covered in class, feel free to ask them. I will happily answer, though my schedule today is such that I may not be able to answer questions in advance of tomorrow's Slytherin/Ravenclaw lecture.
