So... what would you say Aya is? She sounds schizophrenic in that she has multiple distinct personalities, each with various emotional states, however she isn't delusional, hallucinatory, or paranoid.I guess it's more "Hollywood" schizophrenia. I don't know. Point is, she has rapid and unpredictable mood changes. Almost like she gets bored with one personality and thus switches to another.

With multiple distinct personalities (in reality) you "lose" time. She would have no memory of what she'd done while in another personality and they would be COMPLETELY different. A different cadence, different tone, different style. This would also make her dangerous on a level that she wouldn't be able to be an X-Man unless she was heavily medicated - and maybe not even then. 

The personalities are not aware of each other with schizophrenia and they act independent of one another. With DID they can be made aware of each other (which is how you treat it). She seems more like she's in a manic or hypomanic state. Which also needs to be treated with medication. Like I said, do whatever you like.
