A person under the babbling curse will babble whenever they speak, a leg locker curse would lock legs together so the victim will probably be bunny hopping. A hair loss curse will make hair fall out and..." Sarah thought she had given enough examples, "if a person has been killed by avadra kadavra, there will be no signs of any trauma, but a shocked expression on their face"
