It is even possible that DD himself sent Ron, the 
young version of himself, to the past in order to become DD and carry 
out this special mission. OK, this might be just a tiny bit 
confusing, but it can be made to work using WDID without any 
inconsistency. Only it does not change what Ron knows. He knows about 
many events that are going to happen and he can't prevent them, he 
just has to sit and watch them as they happen. IMHO this part of the 
scenario really sucks, but no account for personal tastes.

vmonte responds:

I like the idea of Ron having a special mission but I'm not sure I 
understand the theory that you are allowed to go back in time as long 
as you do not change anything?  Why go back in the first place unless 
you want to change something?
