Lol, Lavi's possble insanity is more subtle then the others. Then again Lavi's character is overal subtle, so it's fits. I think after the Road dream he is a little more together (pun not intended) but I still view him on the insane list for not wanting to stop the human races extinction (I'm sorry but that's just crazy valuing the opinion of a old guy over you're entire race no matter what. Makes me worried if something else happened to Lavi other then watching battles to make him disagreeable to his overall kind).

Poor Lenalee probably doesn't remember a day where she has ever really been totally sane. XP Thank god she's way more stable then she was as a kid.

Allen, I have nothing to say other then any psychologist would have a field day with him. Or lose all their hair of they had not already.

Kanda is the angsty suicidal flower girl, uh I mean boy. =P And yet I still think of him as the most sane of the four (I have a feeling though I possibly won't after finding out more about his past more though). XP

The Earl is without question insane. Whether he has a good reason for his insanity or not, who knows? I am eager to find out why though since it seems he's doing it for more then just for the heck of it. He doesn't seem that crazy really so mauch as eccentric.

I'm not going to touch the noahs I think. XP

Cross I don't know. He seems pretty stable, I think he's just really mysterious so it's hard to tell. I'll go with sane for now.
