Well, the question is who was she referring to with "her" when she said "what will happen to her". That could be Shay as well.

@phantom42 I think that's what called "a cliffhanger".

She could've been talking to Mark, referring to Gracie.

Or she could've been referring to Marion, or to Krystal.

@SQB depending on who it is, it's still a massive cliffhanger. if it's a prolethean, not so much. but if it's crystal or tony, or paul (yes, i know), that's even more of a tease than not showing anything.

There aren't that many people who she could have been talking to. Ferdinand, Marion, Shay, Mark, possibly Paul, or an yet unknown person. If her murderer was unknown, then the "her" she was referring to must've been present.

I can only imagine Krystal or Shay being present as the "her" referred to. Possibly Marion.

Wikipedia outright states she was referring to Cosima.
