Gogol 'reattached' Rollo's head?
Of course, we know that Gogol was Rollo in disguise to trick Orlac into thinking he killed his father, but that's not the point. I just find it crazy that Orlac would just accept that explanation without hesitation. "Oh, he was decapitated but Gogol sewed his head back on and now he's all peachy!"
I can accept it since suspending my disbelief isn't too hard with a movie like this. But still, it's absurd.
