Using this ability, Rowan and Suzie will be able to change their own appearances and the appearances of others. They will not need physical contact to do so, but will need to be close to the person and able to see him or her. The change will happen instantaneously. They will be able to change either small details or an entire person, and will also be able to copy the appearance of another perfectly for impersonation. However, they will not be able to affect people's bodies in other ways, or copy other traits such as personalities, abilities or memories.
