Canon question (DH)...
When Voldy had just killed Harry's parents, leaving Harry orphaned, and Dumbledore is speaking with Snape about needing to protect Harry...
Snape is refusing, telling Dumbledore that the Dark Lord is gone for good and that Harry does not need protection.
Dumbledore tells Snape, instead, that Voldy will be back.
Question:How does Dumbledore know that Voldy is not defeated for good?
It can't be the prophecy that Dumbledore heard, b/c Snape eaves-dropped on it and he is not convinced that Voldy is coming back.

And also, just what influence it might have made on Albus to see young Tom wearing a ring with the mark of the Hallows on it.
At that particular point in time (sometime after Tom's 5th year) Grindelwald is active and Albus doesn't appear to be doing anything about it. There is no telling whether Albus has an inkling as to whether Grindelwald is using the Elder Wand or not. And Albus doesn't yet know about the Potter Invisibility Cloak either.
So - I now wonder whether seeing a ring with the Deathly Hallows sign engraved in the stone, being worn by a student that Albus highly distrusts might have affected Albus' finally going after Grindelwald. And does Albus actually recognize this ring as a Hallow? -- Hwyla
What he thought when he saw Tom with the ring? I don't know if he recognized the ring as the resurrection stone or thought it was like Xeno's necklace - a piece of jewelry originally belonging to a Hallows Quester. Perhaps he thought Tom got involved with the Hallows Quest. (This could work with either identification of the ring.) So he should have been on the alert that Tom was pursuing immortality (even though the ring was somewhat of a red herring, as Tom didn't recognize the stone for what it was).
An interesting question was who was the person who offered Marvolo Gaunt a nice sum for the ring back in the day (some time before Merope left home in 1925). I think it was swythyv who suggested the person may have been an agent of Gellert's.
However, we did hear from Krum that the symbol WAS used by Grindelwald as his own symbol - hence the reason he got so hyped up about it when he saw Xeno wearing it at the wedding. So, I think I'm going to lean towards Albus seeing it as a sign that Tom admired Grindlewald.
We are not exactly sure when he began wearing it. I tended to see Horace's memory as taking place during Tom's 7th year. But he would have had the ring since the beginning of 6th. I would HOPE that IF he had been wearing it during 6th year that SOMEONE would have questioned him about it before making him HeadBoy - but as we have seen before (with James) one doesn't really have to be exemplary to become HeadBoy. -- Hwyla
When did Tom kill his father? Well, that depends. In GOF we are given the date of 50 years before summer 1994, before Tom's 7th year. In HBP Albus says it happened when Tom was in his 16th year - did he mean the summer he was 16 (actually his 17th year) - ie 1943, before Tom's 6th year or actually in his 16th year, ie when he was 15, in 1942?
I agree with Jodel that Tom's conversation with Morfin implies Tom only learned that day that the Gaunts were Slytherin's heirs and that his father was the Muggle living next door. Since diary!Tom knew these things this places the acquisition of the ring in summer 1942. But the other 2 readings are quite plausible, with a different interpretation of Tom's interaction with Morfin.
Anyway, Jodel goes on to suggest that it was the conversation with Morfin that motivated Tom to seek the Chamber of Secrets in earnest, and the experience of modifying his memory that led to his experiments in recording his own memories in the diary. Maybe.

I doubt it. Would anyone have questioned the Lovegoods? The ring did nothing to Horace's trust in Tom.
