That, more than than anything that came before, suggested Margot at the very least knew the truth about Alison's identity. However, I Know What You Did Last Summer'due south season 1 finale confirmed it was Margot all forth. Margot killed Helen, Alison's mother, Johnny, Riley, and the cop who was looking a flake too closely at the case.

Information technology'due south all pretty twisted.

Riley confirmed to be alive in I Know What Yous Did Last Summertime's season 1 finale could besides hateful trouble for Alison and Margot in season 2. Later on all, she is the merely other person too Dylan who poses a threat to them. She might non take seen who stabbed her, but her render could pose a problem for the murderous duo. Information technology'due south possible she might go see Dylan in prison, who volition tell her the truth and lead Riley to mess with Alison and Margot as payback for what they did and how that led to her near-death feel.
