I'm sure theories about what happened to Bella's husband James have been talked about a lot already so sorry if I'm about to write something impossible, but there is this line "I have forgiven him..." which Bella thinks about James. I dunno why, but I got a feeling that maybe they had a kid together and tragically James was involved in demise of that kid. The hidden room could be kids old room or memorial type thing. James could either be in mental asylum or went away in grief (most likely suicide) and never returned. As latest update shows (and even before that), DPC doesn't mind having some grim realities within the game. Is this a reasonable theory or am I just clueless idiot?
