I find myself puzzled by the dialog that happens during the moathouse ambush. I don't really understand what their motivation or the point they are trying to make. Back in hommlet, they seem keen to fight the bandits, but now they turn up with gnolls in tow and seem upset that I've killed the boss. And as for the monk's philosophical musings, I've no idea what he's on about. Maybe I need to craft an amulet of wisdom. In my head, I've decided that they are simply super grumpy that I stole all their gear while they were passed out drunk. Does anyone else have a better explanation? Thanks.
I've never recruited these guys, but they are scripted to turn against your party under certain circumstances. I don't recall if they are affiliated with the moathouse bandits, or whether they are a separate faction who see their chance to replace them when the party is stumbling home after a big fight. Either way it's an absolute zinger.
That's inaccurate - the description of Turuko and Kobort says they will spy on larger parties returning from the moathouse and attack when they're reduced by deaths and wounds.
@MrPhil - to answer your question, the dialogue was cobbled together from existing unused or little-used dialogue choices for those characters. There was initially more, Gaear toned it down a little and I think the final outcome is fantastic - but when you are using pre-existing assets, you are (obviously) limited. Re their motivation - they're (Kobort, Turuko and Zert) all baddies who are scripted to turn on the party if the become weak or vulnerable. Philosophy-wise, players tend to not take them along, (knowing their utility will be finite) so this allows them to have an impact in the game otherwise. Fun fact - Gareth Edwards did something similar for Rogue One, using outtakes of the Death Star fight to create authentic-looking footage of Red and Gold squadron. Can't tell you how much I loved act 3 of that movie.
