After you talk to Jobst during epilogue, but before setting out with hans Capon to end the game, go see Theresa one more time. There is one more conversation.
It’s a conversation about Henry being radzig’s son. It’s not a big thing but I thought it was a nice addition.
I found that too, and thought it was a nice thing to include, given the amount of work likely required to have it made. Generally, I wasn’t too impressed with that particular plot twist, though. Immediately made me think of Star Wars.
