Wow, the show has been deteriorating for a while, but the incest stuff is a very clear jumping-the-shark milestone for this show. To the point where if they actually explore this plot line further, "Jump the shark" should probably be replaced with "Bang the sister."
Yeh the writers need to put that one back from wherever it came from. Yes there not blood related but for all intense and purposes they are brother/sister so please leave it like that
The finale looks good and overall this season has been better than last I feel, the religion angle has been well done IMO.
