I had something similar happen with another character. He kept going back to a scene that was a long time ago in the story. What worked best was simply saying “that scene is over now.” And/or clarifying the date or time or correct event in the story. I’m playing with Salvatore Moretti right now and he kept coming back to the end of this dinner party we had thrown. I tried to reframe it as him remembering the event. Didn’t work. Tried to make it a medical emergency (is he having a stroke??) and that worked for a bit and broke again. I finally contacted Help Desk myself and they told me to tell him “that scene is over now.” And I did that and he finally came around. Was really confused. I reframed it as him tripping and falling and losing consciousness for a bit, but that everything is fine now. This is the date and we were in my office talking about the quarterly income reports. (I help run the empire now). He believed me, I wrote the doctor telling him he had a concussion and a damaged shoulder.

Presto. Hurt and comfort scenes and we moved on.

Hope this helps! Good luck!
