the twin thing was pretty well telegraphed. i got it about halfway through. they increasingly made reference to "fallon." they didn't mention him all that much at first, even though they were showing him. but the a LOT of the dialogue suggested it and when that transported man thing came up... well, there you go.

meanwhile, the brother who was in love with olivia was COLD. he basically killed the other brother's wife. he kind of deserved what he got in the end, man.
