Question re The Riddle House

[marephraim]

No: HPFGUIDX 46526

Forgive me for this as I'm sure it _must_ have been discussed at 
length before. My wife and I are now both on our fourth read of the 
canon (for me this is since last Christmas, JRK hurry!). 

In Chamber of Secrets Tom Riddle speaks of living in the orphanage 
because his muggle father turned him and his mother out when he 
discovered she was a witch. He also indicates that after Hogwarts he 
disappeared (figuratively speaking) so that no one later realized 
that Riddle and He Who Must Not be Named were one and the same 
person.

In Goblet of Fire the deaths at the Riddle House included the 
elderly Mr & Mrs Riddle and their grown up son, Tom. 

Question: Is this a Flint? Are we to assume that the Tom Riddle of 
CoS, because the distillation of his 15 year old self, could only 
assume what he would do after leaving the school (the manner in 
which the Diary was made and the potential personality limitations 
on the TR who occupies its pages itself is thought provoking)?

Further, it seems the old saw that You Know Who is ALWAYS the 
antagonist in HP books doesn't hold for CoS. Sure TR is the trouble 
maker, but LM is the instigator. (I know I'm going to sound like a 
dottering old fool for saying this but...) are LM's motives for the 
diary truly clear in CoS? Did he intend revenge againt Harry, 
revenge against the Weasley's? Revenge against m*dbl##ds at the 
school? Was he somehow following He Who Must Not Be Named's wishes 
(Imperius Curse)? -- although this latter one strikes me as highly 
unlikely.

Again, forgive if this has been discussed before (and more so if the 
FAQ, etc., cover it in detail). Remember reading those books four 
times in a year is hard if you're tring to hold down a job and have 
a meaningful muggle life on the side, too!

Thanks for any enlightenment on this ("Lumo!")
