Answers Revealed (The Lying Game - season 3)

For those of us who have craved an ending to The Lying Game (by Sara Shepard) the tv show. It ended on a cliff hanger. Who killed Theresa? Who killed Derek? Who helped cover it up? Why did Thayer have the murder weapon? Will Ethan forgive Emma?

I used Chat GPT to create an ending for all of us who have waited this long for some answers. All of the topics are based on what I wanted to see from the shows ending.
