 Donnie Darko gets along badly with his family, with his teachers and with his classmates; but he does manage to find a sympathetic friend in Gretchen, who agrees to date him; and he has a compassionate psychiatrist, who discovers hypnosis is the means to unlock hidden secrets. His other companion may not be a true ally. Donnie has a friend named Frank, who is either a large purple bunny, or man in a large purple bunny costume. Either way, Donnie is the only one who can see him. When an engine falls off a plane and destroys his room, Donnie is not there. Both the event, and Donnie s escape, seem to have been caused by supernatural events. Donnie s mental illness, if such it is, may never allow him to find out for sure.
