I don't own Donnie Darko or the characters or any of the theories that are associated with the movie. The plot for the story comes from these websites I found with scientific explanations but I warped them to suit my own need for this story.

The websites are:

. /explanation/

. /unanswered-questions/?post=true#blog

. /alternative-explantions/

I will give a brief outline here of what is going on with Donnie and why this all happens to him. Of course this is not a legit theory, just one that suits the story I want to write. Please review with your opinions but be respectful.

-Donnie is a superhero like Dr. Who but it is not fun. It is a curse and he constantly ripped from Time Line to Time Line

-his whole purpose is to save the world from TU created by any kinds of disruptions

-when ever he wakes up laughing it is because he recalls everything that he has ever done (including what it will all lead to -which is nothing-) and he laughs at himself because he doesn't know why he tries. But eventually he forgets when back in the timeline.

-the last thing that occurred (the movie) was different

-in every TU or strange occurrence, there is always someone who falls in love with him (usually Gretchen but sometimes Joanie) because he is the chosen one and because it must be done to save the world and they are manipulated living

-the women in his family know about him at length and know why he is so weird

-this explains why his mother is odd like him (she had the curse and passed it on)

-why no one cried at the beginning when it crashed in his room because they knew he was back from a mission but at the end they knew he was dead

-the reason the mother wasn't upset was because she knew he was going through deep suffering

-the only way it could end was if he died or passed on his gift, ( Roberta gave it to his mother when she taught her in school-in this story Rose went to that school as a child and was given the curse by Roberta which explains why Roberta wrote the book-and his mother gave it to him at birth)

-if it is not passed on it finds a new person to save the world

-the strange thing that occurred was finding out Cherita had a crush on him

-Cherita had nothing to do with the any of the plots and never was a love interest and never did anything to manipulate Donnie into saving the world

-the knowledge that someone could love him beyond his super hero qualities is what made him come back and relinquish his abilities

-instead of dying he rolls out of bed and only hurts his arm in the process and chooses to remember everything that occurred in the last universe but that is it
