I  can't help thinking that this is some kind of follow up from the 
altercation on the train. There's foreshadowing from CoS and 
PoA that  Lucius Malfoy would retaliate if somebody injured his 
son. Maybe the Dementors were sent to apprehend Harry and  
he fought them off.

Then there's Molly's mysterious comment. When *what's* 
finished? A meeting of the supersecret Order of the Phoenix 
perhaps?
