Isida,
I included Mel's 4 most promonent personas in the RG (under appearance). Only one is fully developed, since she's been living that life for almost all of her life. The others are ones she is developing in some way. She may develope more as life goes on.
Part of the way I see her persona's, is that they are a way for her to hide from some of what's happened to her. She can immerse herself, and hide a part of her true self from the hurt. This is not true multiple personality disorder, though there may be some traces of it, but deep down she's still Mel, and the personalities are more acting than constructed by her mind like true insanity.
I did put an explanation of each persona, and how true to it she can realy get. Some of them are idealized, and she isn't able to realize them fully yet.
