The two NPCs for this quest both provide greetings like I've already accepted the quest despite it being my first time talking to them. Several dialogue lines are filtered such that they will never appear.
Balyn Ilvenes in Indal-ruhn still has a 'Services' line that implies he offers boat travel, even though he's now just a dockworker and provides no services: "Rolis Hlor over at the west end of town has a nice selection of everyday wares. For anything more specific, you'd want to go to Almas Thirr. Want a ride?"
Inerisa Tharys' line for 'Background' topic is "I'm %Name, I sell various goods to the people of Tel Ouada." even though she's a commoner and provides no services.
She also has a pretty redundant 'my trade' line, though that's just old TR quirks, I guess.
Although the FG quest 'Guar Duty' has been deprecated, there still is a version of Erdlan Galelan that is in Erdlan Galelan's Shack even though the main version of Erdlan that's involved in a quest (TR_m1_Erdlan_Galelan) is outside.
Hlorandus' sewer exit should probably be updated to use T_De_DngStrongh_X_Sewer_01 with ex_vivec_grate_01 now that we actually have a dedicated sewer exit for the set
Some dialogue on the "go free" topic is filtered very generally (screenshot attached). Any slave in map 7 will end up with this dialogue if there are no lines with higher priority and the player has the "TR_m7_HL_FG_Q5_SlaveKey." Presumably this topic should be filtered to a Specific Cell or NPC
