>I've always thought that Petunia is a squib and that Lily (contrary 
to Tom Riddle's opinion and Dumbledore's statement to Harry) is a 
descendent of Slytherin.
This theory also gives us a way out of the "how do we know he's 
really dead this time" maze. Now all I need for complete happiness 
in this world is for the Weasley clan to provide the heirs to 
Ravenclaw and Hufflepuff (yeah, yeah, both females, patrilineal 
inheritance: I say, mitochondrial DNA, so there!) Then Harry can 
marry Ginny, reproduce, and all four founders can rest in peace.

C'est moi:
Wouldn't it make more sense, knowing what we do about James and 
Lily's teenage behaviour and James/Harry/Riddle's appearances, to 
suggest that *James* was Slytherin heir to Lily's Gryffindor?
