Red Riding Hood (film)/Fridge

Even if you remembered that in the original fairytale a woodcutter saves Red from the wolf, the film has two woodcutters who'd have a personal reason to save Valerie, so knowing the original story provides you with no useful hint as to who the wolf could not be.
Father Solomon's children may seem strange,given he is a priest and apparently pretty high ranked. But if you look at the cross on the roof of the church, it is clear we are dealing with an Orthodox village, hence, it makes sense for Father Solomon to have children as Orthodox priets aren't banned from being married.
Anyone thinking of using the original fairy tale (where Red is saved by a woodcutter) to eliminate who isn't the werewolf would be disappointed as two of the main suspects, Peter and Cesaire, are both woodcutters, so either could be the rescuer.
This is more of a supernatural geek Fridge Brilliance. Father Solomons story of his wife draws its roots from an early werewolf tale of a professonal Werewolf hunter who shot a silver bullet at a werewolf and as it ran, he saw he had severed the paw from the wrist. He didn't find the body, (A little fuzzy if he fould the paw or not), but the wolf never attacked again. Years later, a doctor heard the story and confessed to bandaging a womans stump of a hand when she claimed she lost it to a barbed fence.

As far as Suzette (Valerie's mother) knows, everyone she loves except Valerie -- Henry's father, Lucy, and Valerie's father (though whether or not she truly loved him was debatable)-- is dead, and Valerie has moved into the woods, and very well may vanish herself in the near future. Poor thing.
A different sort of Fridge Horror comes up when you realize the film implies Cesaire very well may have turned his own mother into stew, which Valerie eats a bite of before stopping herself. Something very similar to this happens in older versions of Red Riding Hood.
Plus, remember Lucy being in love with Henry? Well, this means that she had a crush on her half-brother. Which is stated outright from Suzette as to why she put Valerie together with him instead.
- Incest Is Relative, but she probably doesn't even know Henry is related to her.
