So i go through all the motions at the ghost farm and in modok, then i head off to the den to get karl. For some reason i didn't see any dialog option to tell him it was safe to return to modok, very veyr odd. All i could do was give him several different drinks or ask him about his story. I ask him about his story again and now i can't talk to him anymore. All i get is the text above his head about how the ghosts can't get him here.

Will i get another chance or did i somehow ruin the quest? No idea how or why it wasn't giving me the dialog option i needed.

You must have angered him the first time you met him. I think you have to buy him a drink or give him $100. He'll pass out, but if you wait a couple hours he'll wake up and then you can continue the quest.

ha whoops. No i just jumped the gun asking the question. Been a long time since i played this part of the game. Turns out all you do is get his story, then report back to Modok and tell the mayor jo guy that karls in the den. Then after that is when you go back and get to tell karl all is well and receive the rest of the exp points and all that.
