Yeah, I was able to get the oil from him and have him demo it for me. I also spoke about his past with him, spoke to Lorzan about him, and had him divulge everything about the orphanage. Now I am just in a constant text loop where he just keeps talking about the same orphanage. I am not sure if I sold him everything...I sold him the Gold ore, Ring, Moss, Stone Snail, Normal Mushroom, Water Mushroom, Forest Mushroom, and a Rock Mushroom. That's what got me to where i'm at. What am I mising...?
I am still unable to unlock scene 10, but I was able to unlock scene 9. You unlock scene 9 by maxing our your relationship with Lozran, completing all of the games quests, and finally saving Gerald . Just try to complete all the quests, keep flattering Lozran, do one of his first scenes with him, then, once everything is done and Gerald is gone, go back to the inn and speak to him.
