Besides Samantha, I also remebered a few things I never got to see again after they were introduced

- The shady guy that was talking with Josef in the garage told me to visit him nearly at the start of the game, but I never found his location in the map, and the journal doesn't say anything

- The demon lady that cames out of the portal in the shrine and I let go free never appeared again, do I have to do something very specific to make her show up or is it content in development?
