CGrascal said: Well since Lilith is now a part of Morrigan and her own individual to an extent, having both Mokas be Morrigan and Lilith makes sense.
If you think about it, Inner Moka was there first and then after Moka went to the human realm she became that Moka. Inner Moka was the Original Moka (Morrgan) and Outer Moka (Lillith) would be seen as the weaker version of her that became her own person.
