Yeah, very cultish. I thought for a moment they were trying to be like the Bible story where the guy had to sacrifice his son (I'm not religious, so excuse me not knowing their names). Is this the first time they've shown the Mittelos guy (Mascara Man or whatever) on the island? I didn't realize he lived there.
Yes, I thought maybe it was a test, to see if he would kill him. I thought that maybe Locke's father was an Other until Ben wacked him.
I also wonder if they staged the plane crash so no one would be looking for them. They seem to be very powerful. Next week is about Ben, so maybe we will get some answers.
