User blog:Morgan silve/Hollows

Over the days, I have been wondering if Hollows were really "Hollow" (hard on the outside, empty in the inside) I'm really confused because when Orihime was healing Grimmjow, you can see the arm's bones regenerating. Then theres the Hollow whole... You see the black around the edges. Also, arrancars bleed when they are cut. As shown to the left of this description, wonderweiss's head is totaly empty. Could it be that when an aarancar goes into ressureccion, this happens to them?
