From the very beginning the "twist" is obvious. It's clear from the start what the real deal is. But instead of our detectives solving things realistically, they start jumping to conclusions that are not obvious from the clues they find.
When Benson and Rollins find photos of the "rapist" snapping a selfie above an unconscious woman, they immediately assume the woman was aware of it even though the photo clearly shows she was not awake. Not only that, but they immediately jump in and start accusing her of having a relationship. Based on those photos, they would not and could not have made that assumption. The writers just got ahead of themselves.
So the rest of the show, as it unfolds, feels very unreal and scripted. It's unfortunate that there wasn't much more to this episode. It could have been told in about 10 minutes.
