You may have already discussed these questions already, but here goes:
1. In the GOF how could Voldemort cast spells from his chair in the 
Riddle house if his arms were too weak to hold a wand?
2.  Does anyone think that there is a couple time lines going on 
here? Harry, Ron, Hermoine, & Neville vs. James, Lily, Sirius,& 
Pettigrew?
3. How come some wizards can conjure up platters of food, while poor 
old Mrs. Weasley has to cook with her wand?
Also, I think I have come home...
