 @m-kiewitz:
 > somehow warp to this location and try to get the dialog

 The room inits itself differently with each arrival as the story
 progresses. Unless there's a way to directly call script procedures from
 the debugger, setting specific plot flags to time travel would be really
 cumbersome.

 They're stored across a range of globals, referenced together as an array.
 Each global integer is a bitmask representing several flags mashed
 together.

 * "proc0_2(n)", "proc0_3(n)"
   * Not clear on what they each do, but definitely setters.
 * "proc0_4(n)"
   * Tests the given flag.

                         [global500 (/ param1 16)]
                         (~ (>> $8000 (mod param1 16)))
                 )

         (return
                 (&

                 )
         )
 )

 The debugger CAN set a global. What's complicated is choosing the value to
 set the desired bits. I'll see if I can determine the magic numbers
 driving their dialogue.

 Of course, if digitall can open my savegame, well, they'd be there
 already. :)
