Need help with Visitors: how to access other conversation options

[MigCas]

hi, just registered here to ask a few questions. I've been playing Pillars of Eternity for a couple of weeks now. Let me start off with this one. I know this may be an old topic, but I kinda need help with one.  I just so happen to check some information about the game, specifically Caed Nua. link over here: http://pillarsofeternity.gamepedia.com/Caed_Nua#Adventures

 

I noticed that there are special guests (bad and prestigious ones) that actually provide other conversation options. The ones i actually have in my keep now are Lord Byrnwigar (bad) and Lord Sidroc (prestigious). For Byrnwigar, I wanted to have the option of hanging him to actually gain +3 prestige and probably help Sidroc with some other things. However, whenever I try talking to them they never open a conversation window and only say one line. Sidroc doesn't have any other options in the Keep menu and Byrnwigar has only two: "Pay Off" and "Send Escort". 

I'm wondering if i'm missing something in the game's progress or if there's a bug. Any suggestions?

Pay Off and Send Escort options are only available for Supplicants. Visitors will have dilemmas (dialogue interactions). After you complete a Visitors dilemma they will sometimes return to the Stronghold as prestigious visitors only granting the bonuses.
