All the Incandenza boys are deformed in some way, in that way all great athletes are deformed. and of course there is also Joelle, who hides her deformity, whatever it might be, behind a veil. but no one thinks of them as deformed--even Joelle, which is odd, since she calls attention to her (possible) deformity.

Mario, of course, is also an innocent, which is something the others are not. Orin, Hal and Joelle are all very cynical. Perhaps that cynicism is also a deformity to Wallace--they use it to escape themselves and escape others, where Mario is able to use his deformity to get closer to other people. It's funny--because most of the protagonists in the story are so extraordinary, Mario becomes the most relatable of the non-Ennet House residents, and ultimately the only truly human Incandenza.

Altho I really like Avril. I'd like to see Julianne Moore play that role. She'd be an excellent Avril.
