Remember when Harry claimed he was Neville Longbottom on the Knight Bus?

Remember when Harry announced himself as Neville Longbottom on the 
Knight Bus and we later find out that the prophecy could have been 
about Neville?  Voldemort chose Harry (whether by accident, fate, or 
on purpose).  But JKR foreshadowed the idea of interchangeability 
with the bus incident.

I have a feeling the same kind of thing is going to happen with Ron.
If he gets blasted in the past and somehow gets stuck there (yes the 
Ron=DD theory) I could see him jokingly calling himself Dumbledore 
without realizing that he in fact will turn out to be this very 
person.
