Dual persona

Lelach is also shown to have two personalities: A serious, more stern one and a rather broken minded child, often speaking with a stuttering tone. He also has a tendency to speak in third person, referring to himself, and others, by name. Should it be noted? I feel that him stated as "insane" is close enough to even bother with that.

I definitely think his stutter and him calling everyone Lelach should be noted, I'm not sure whether or not the multiple personalities should be noted or not.

I think its fine to say he has multiple personality disorder.
