Did you read Satella's page?

Sigh, here : Contrary to popular belief, Satella and the Witch of Envy are separate personalities, formed when she took in incompatible Witch Genes. The two personalities tend to fight each other. Both personalities love Subaru, though the Witch of Envy personality is much more aggressive about it, while Satella is much more reasonable and cares about his well being.
