Emma Desmond

Emma Desmond is Julian Albert's Sister. As you know Julian Albert is Alchemy. We first saw Emma in the Indus Valley 4 years before he met Barry Allen. He was looking for the philosophers stone. His sister and a unknown crew found the Philosophers Stone. Obviously Savitar made him think his sister is Alive and he tricked him like Emma was alive. Soon after Julian found The Philosophers stone and became Alchemy
