Sirius’s letter was almost as short as the previous one.
Be at stile at end of road out of Hogsmeade (past Dervish and Banges) at two o’clock on Saturday afternoon. Bring as much food as you can.
“He hasn’t come back to Hogsmeade?” said Ron incredulously.
“It looks like it, doesn’t it?” said Hermione.
“I can’t believe him,” said Harry tensely, “if he’s caught . . .”
“Made it so far, though, hasn’t he?” said Ron. “And it’s not like the place is swarming with dementors anymore.”
In this context above which comes from Harry Potter and the Goblet of Fire, what does Ron mean? I know "He hasn’t come back to Hogsmeade"'s meaning but after adding a question mark, did the meaning change to the opposite?
Thank you very much!
