I fear he does not say anything in the lines of that.
I can only say the following dialogue tree: (except from bye bye, exiting dialogue)
0 (root)
1 "What do you have to trade?"
--- 1.1 Do bussiness, OPEN BARTER
--- 1.2 More questions, THEN GOTO 0
2 "What can you tell me about this town?"
--- 2.1 ask about Bed and breakfast, THEN GOTO 2
--- 2.2 ask about slaughterhouse, THEN GOTO 2
--- 2.3 ask about tradinghouse, THEN GOTO 2
--- 2.4 ask about tannery, THEN GOTO 2
--- 2.5 ask about white building, THEN GOTO 2
3 "What do you do here?"
--- 3.1 Taunt: Wow what a popular fellow you are, THEN GOTO 0
Im going to try to delete MODMAIN.SAV from my savegame and reload the area, hopefully it wont corrupt my data. Im going to backup first though.
Any other ideas are welcome!
Kind Regards[/i]
EDIT: Deleting the area caused Fallout 2 to crash, I created a new game however and went to the town, saved a temporary file and copied it over to my original save file. It worked.
Now the important part is to say: "What do you want me to do, you know I cant make it rain right?" and none of the other options, all other options will get him to exit the conversation and say "another time" killing the line of dialogue forever (it seems).
The bug here seems to be that if you tell him "Just tell me about the GECK and ill be on my way..." he wont give you another chance to help him later. (even if he gives reference to talking to him again).
