Can you give us a list of characters who prevent scenes w/ other characters if you ignore/avoid them? Lower in the comments you mentioned that two of Sasha's scenes are unavailable if you skip someone else, and if it's going to be like that, it would be really handy to have a reference sheet so we can pursue who we want to fully!
i'm currently in the process of a major overhaul of my game's ui/ux and replay gallery, and locked scenes will come with a hint on how to unlock them, but for the most part it's super easy to see everything you want. the game is linear and pretty telegraphed. that other comment, for example: he missed a sasha scene because he rejected a prompt from another character while sasha is directly next to you in the same room :)
