said Dumbledore used time-travel extensively, meaning to get the
memories, but really there's no *proof* of that. It's odd how he
conveniently reached Bob Ogden, Morfin and Hokey right before each one
died, especially Ogden whom Dumbledore said died 'some time ago'. That
would mean Dumbledore was tracking down memories long before he put
together the bit about the Horcruxes and my impression was the diary
tipped him off and started his search.

the circumstance.  So he didn't follow the rules of time travel for
some reason.

Carol responds:

I don't see the oddity. Even if he didn't yet suspect Horcruxes, he
certainly suspected that Tom Riddle had killed his own parents and
framed his uncle, just as he knew that the Muggle, Frank Bryce,
suspected by the Muggle police (but fortunately not arrested) was
innocent. ("I read the Muggle papers, you see.") He couldn't interview
Frank, and really, there was no point in doing so, but he could easily
talk with Ogden, whom he'd have needed to see before interviewing
Morfin, and talk him into giving him the memory of his encounter with
Morfin, along with the true memory of what happened with Tom Riddle if
he could get it. But Morfin died before his name could be cleared, and
 perhaps Bob Ogden died soon afterwards as well. (Could he have been
another of Tom's murders?) As for Hokey, DD would again have suspected
that Tom Riddle was responsible. He knew that Tom had disappeared
immediately afterwards, and he probably knew that two heirlooms, one
from Slytherin and one from Hufflepuff, had been stolen from her. He
would have visited Caractacus Burke (we see only part of that
conversation, where Burke rises out of the Pensieve, Trelawneylike, to
talk about the locket) and learned that Tom had visited Hepzibah just
days before her murder. And that would have led him to Hokey, whose
memory he would take as he took Morfin's, presumably with permission
from Bob Ogden if he was still alive.

No coincidence at all, really. And if he didn't suspect Horcruxes
after Hepzibah's death and the theft of the locket and cup, he
certainly suspected them when he saw Voldemort's altered appearance
when he came to apply for the DADA position.

Carol, agreeing that the two watches are intriguing but not that Time
Travel was required to obtain the memories from Hokey, Morfin, Ogden,
or Burke
