It's still implied that players will discover new characters throughout the game and discover their identities—spoilers. You can remember the characters' names in the Dream World by revisiting previously completed scenes.
what I was more leaning toward and kinda meant is that it this gallery would be something where characters you had already met would show up because I have already forgotten who in the example orchid is and instead of having to scroll through many scenes to find the exact one where orchid shows up it would be nice to have a page in the game where all the characters you have met (and can get scense with (like orchid)) would show up so you could more easily know who the character is and where they can be found
