Could anyone else tell who was beneath the mask? (Spoilers)
The moment Frank started speaking in German to the visiting family at the cabin, the first thing I thought of was Archie Hicox's strange Piz Palu German accent. After that point I just pictured Fassbender under the mask, and the more I watched it that way, the more it made sense. When it was revealed that it was actually Fassbender, it both blew my mind and left me completely unsurprised at the same time.
Honestly, I'm a little high right now and this whole sequence of events tripped me out. I was just wondering if anyone caught it.
