Slughorn handed Theo a scroll of parchment with each of their names written clearly in looping calligraphy. "We need each of you to sign this before leaving the Dungeons today, there is a charm on the parchment so you can't tell anyone about this - willingly. If one of you decides to  not go through with the process, it will be as though this conversation never existed. You will forget immediately and be none the wiser to your fellow students becoming animagus. As this is a very serious, life altering process we want each of you to produce one 3000 word essay on the pros and cons of becoming an animagi and base your decision on your findings. We will not be taking answers from you until 1900 on Hallows eve."
