Biography
Because Danny appeared out of nowhere, Hannah Fairchild thinks that he is a ghost. It doesn't help that he survives numerous nearly fatal accidents, which would kill most people. His mother is also deaf, and Hannah believes at first because she can't hear her, then she is a ghost, too. Danny soon discovers that Hannah is the real ghost, and is scared. Danny later decides to stink bomb the mean mailman, Mr. Chesney, only for it to go horribly awry. Danny winds up failing to light the fuse and the house catches on fire, leaving Danny trapped inside. Danny is nearly burned to death, but Hannah arrives and plays Chesney's piano, alerting him of someone inside and allowing Danny to survive. Hannah later joins her family in the afterlife.
