Alright, so using the power of the Dude's juice, I found the bridge leading to the cave where Katya hides her frozen son. Unfortunately, Katya doesn't like it when people find out about her boy, and after leaving the zone and coming back, she just stares at her hanging laundry. Now, whenever I click on her she "mutters something incomprehensible".
Here's what I've got thus far:
I joined the Grim Jetters (pirate run).
I did this shortly after completing the first raid.
I have since completed the second raid for the pirates, and I have disabled the Rig's sonar (albeit I only killed the Eel standing in front of the sonar itself).
She still "mutters something incomprehensible".
Is there any way to get back to regular dialog. I have a spare save from before I did this, but a browse of the .xpbl files suggests that there is "regular" dialog regarding the fact that I've literally found her frozen child in a cave (I understand that I could have gone in too early, but what would the prerequisites be for *not* too early.).
