Mac: I agree (I think) BUT the single timeline REQUIRES Harry to 
timeturn, that is it can't happen this way unless he does. And 
there's the paradox because if he doesn't TT he gets dementor kissed 
but if he gets dementor-kissed then he isn't there to time turn 
later. As usual it makes beautiful sense as a gripping story (JKR's 
intent) but is nonsense when over-analysed (she rarely apologises 
for this - she writes for her she says and has an excellent feel for 
what will appeal to an audience).

By this logic hermione MUST TT throughout PoA because she already 
has and she can't get to charms after she slaps Malfoy because she 
missed the opportunity (blew it).

Also, has H&H materialised early there would have been two pairs of 
them in the Hospital Wing (but rules say they can't see themselves) 
and had they been late getting back then there's be a period when 
they were gone but not yet returned - i.e. literally disappeared. 
Maybe this is what happened to that OotP member who disappeared 
without trace?

TT also works because people obey the rules and when they don't 
things go awfully wrong (killing past or future selves). What if 
DE's who care little for rules (e.g. wanton so-called 'forbidden 
curse' use) were to time-turn? it seems there are similar perils in 
mis-apparating.
