So I’m playing on PS4 but i can’t proceed any further because all the game tells me to do is go to the upper castle when talking about interrogating a prisoner. When i go there all that happens is there is an empty room and sometimes Sir Hanush and Bernard are there, but when i talk to them nothing happens. Am i suppose to be doing something else?

I just finished killing runt and then went to do a side quest with Sir Capon in the bathhouse.

Anything that can be done about this because my last manual save was many hours before this.

Prisoner is in Merhojed.

I realize but when i go there none of the npcs actually have the option to be talked to

Your only option is to go to your last save.
