HG:
What I find interesting is how oddly cordial Tom Riddle seems during 
this flashback. 
[from pg 246, chpt 13]
' "Evening, Rubeus," said Riddle sharply.
The boy slammed the door shut and stood up.
"What yer doin' down here, Tom?"
Riddle stepped closer.
"It's all over," he said. "I'm going to have to turn you in, Rubeus.
They're talking about closing Hogwarts if the attacks don't stop."
"What d'yeh-"
"I don't think you meant to kill anyone. But monsters don't make
good pets. I suppose you just let it out for exercise and -"
"It never killed no one!" said the large boy, backing against the
closed door.  '

Of course what he's *doing* isn't very nice, but considering this is 
the young VD, it doesn't seem like he'd care to be nice at all to 
Hagrid in this scene. Notice he says 'I'm going to have to turn you 
in.', not 'I'm turning you in.'. That, and I find it odd that they 
both know each other's names. Now Tom might have made a point of 
knowing Hagrid's name (obviously knowing about Hagrid's interest in 
monsters became useful to him), but why would Hagrid know his name? 
At this point Tom is 16 and Hagrid is 13 or 14 and (assumingly) they 
are in different houses (I'm assuming that Tom is in Slytherin, and 
that Hagrid wasn't), it just seems odd that they would know each 
other. 
On a similar note, I wonder if Hagrid knows that Tom later became VD? 
(if he did, I wonder if that would be cause to protest his expulsion 
from using magic?).
