In this chapter, we learn that the seventh witch has made everyone forget about the previous seventh witch, and that the two of them are now linked by the same power. This means that they're both linked by this same power, which means they can't do anything about it without each other's help. They're going to have to figure out a way to deal with this problem, and they don't have a lot of options, so they'll have to do it together. They decide to go back to their homes and find the diary, which proves that they both lost their memories.
