Hm. This actually raises an interesting point: at what point should the players' insights become Kakara's insights? For that matter, given how the players came by this information, does this count as their insight at all?
I know several people speculated that Dandeer was responsible for the incidents, but nobody ever seemed sure, and it never got confirmed. That said, Kakara is very smart, she now has more information about Dandeer and her methods than ever before, and again, multiple people suspected based on information Kakara possesses.
...I admit, I'm tempted to let Kakara figure it out, at least as a shot in the dark.
