Reread the half blood prince last night
Is there ANY chance, do we think, that DD MIGHT be evil, imperiused etc. Quite possibly he has surrendered for good reasons but...
Am trying to reconcile the following
The "gleam" in the eye re harry's blood
The fact that he makes harry obtain slughorn's memory. That is reminding me of the behaviour of Voldemort/ Tom Riddle.
And the ring. WHY is he wearing the ring of Slytherin?
Given that JKRs trademark is the Chechovian gun (ie dropping stuff in quite casually which then becomes VERY important), I am musing on this
The quest for the horcruxes is also interesting to me in that light.
Now I know we don't WANT this to be the case but...
