Everything's great, thank you for such a great review!
I'll start with the gallery. Naomi's gallery has already been fixed, and Sam's was just a typo. I'll fix it and it will be more accurate (sorry about that).
Now about the characters' relationships. There will be some in the future, and some will even be solving in-game, but unfortunately, not all of them will be significant. There will also be DLC storylines related to this, for example, in Bad Sam.
I'm really glad you like the game, thank you for playing it and helping us make it better!
