Keep on mind the flag which is set when you delete the photos can be reset depending on how you interact with Gillian when you meet her. IIRC picking the heart option will put Ian back on that track and block him from opening up to Holly.anyone knows how to unlock the open up to holly option on chapter 11, ive tried many options before but it is always blocked, in a earlier post it said that deleting gillian photos on chapter 3 was the way but i still have the option locked in a solo holly gameplay
