One beast or two?
Early in the film I assumed that Cathal was the beast. Then later it is revealed that Fergal is the beast. So were they both beasts with Beast Fergal merely the offspring of Beast Cathal (as I assumed when watching) or was Fergal the only beast all along and I got it completely and utterly wrong?!
... and if the former, what was the motivation for Cathal to kill his son if Cathal himself was also a beast?
Why also did the mother want to protect the beast? For any other reason than it was her son?
Confused :S
