Una sa lahat Ben is alive.

NOTE: He never tried to kill Ana. He was only aiming for the snake (di to nagets ng nanay ko pati GF ko kaya nilinaw ko incase meron din ditong di nakapansin kasi medyo panget pagkafilm nung snake scene.) Kaya niligtas ni Ana si Ben after nyang malaman yun kasi napatunayan nyang mahal sya ni Ben at mahal pa rin nya si Ben kahit alam nya ng Killer sya.

Proof Ben is Alive;
1.) Anak ng Visayas Ceremony - Others say na baka hallucination at nabaliw lang si Ana, valid point pero may iba pang solid proof.
2.) Plaques and Photos - This scene is POV na ng audience inside the home kasi tulog si Ana kaya alam na nating tunay yung nakikita natin na may plaques si Ben at mga family photos nila.
3.) Elijah - Elijah knows his dad is alive and acknowledge his existence, napakatanga ng mga tao kung iniwan nila yung bata kay Ana at ilang taon ng nagaslight na may tatay sya kung patay nga si Ben haha.

Why did the ending made sense?
From the start Ana had her mental problems and only wanted 100% of Ben's Loyalty. Ngayon kilala na nya si Ben ng buong buo, and she's happier kasi ngayon she has no reason to doubt him diba? ano pa tatagong baho ni Ben? Ben also got what he wanted which is being accepted for who he is.

Why was Ana smiling happily when she saw Ben was outside?
Eto personal theory ko na lang, The final Loyalty Game. Kinwento ni Ana kay Ben na Nanggugulo si Beth sa kanya, knowing na perfect na yung buhay nila at si Beth na lang yung natitirang pwedeng makasira sa kanila Ben decided on his own to kill her while her wife was sleeping.

Twisted part is alam ni Ana na ganito ang iisipin ni Ben and this is why she's smiling. She no longer feels insane, because she knows her husband is. She's happy that she is in control, and she knows that her husband finally passed The Loyalty Game.

The Loyalty Game Ending made sense.
