So I just finished playing the first four Blackwell games and noticed the fifth one has been out for a couple of months, and that it concludes the series. As I was playing the first four games, I was really waiting to find out about Joey, his backstory, and why Rosa's family is "cursed," or whatever you want to call it. Why they are mediums and how far back it goes. I was a little disappointed that I was mostly finding out about the random ghost characters I met, and didn't find out much about Joey and Rosa, until a little bit in the 4th game at least.

My question is, does the fifth and final game have more information about Joey, and Rosa's family history? I don't want spoilers though.

Yes
