While I'm not necessarily buying Hester as Ivala's captor (I think it's a still-unrevealed entity, distinct from the missing tower walker) the cutscene between chapters 2 and 3 strongly implies that one of the remaining threats is female. Ivala says that "Her eye grows ever more powerful." And it seems clear she's not referencing her captor, since that came up up a line or two later (and seemed to imply multiple captors in that case, even though her captor is singular at the end of chapter 4).

The reason I don't think it's Hester is partly because of that same cutscene: "Mortals will reach the Tower soon." I have a tough time buying that Hester is not mortal, given that she's an old woman, and it implies she hasn't reached the Tower yet. Alonon might be an exception, since he was directly referenced after that, but they're also apparently ignoring the Sage of Ghenalon and Ulrissa-Ulrissa almost HAS to be mortal since she talks about her plans to die, eventually.

So I'm left wondering if the hidden Tower Walker isn't someone extremely close to Simon, like Vhala or Esthera or even Carina. It's possible someone has secret motives and a power so subtle that Robin and Riala can't detect it, and are helping Simon only until they can betray him later. But I'm not sure if that's the kind of story Sierra Lee is telling.
