The Death Eaters have made their first attack on London. They are in the school and are planning for a second attack. This is a good plot thats already in the works with several characters. Also, Charles is unstable because the death eaters killed his cousin and are now going after his aunt and uncle. Charles was forced into the death eaters. He wants to quit but this anger still lives on,
BTW: This is out of character, so people have to find out Charles is a death eater on their own
