Good! The CG appears later down the line in the first night between Edwin and Resnick. Go through it all and it should appear, more or less of it depending on choices, but it always appears!
Do you mean the sprites are locked in the Memorium? To unlock those, you have to see the character's memory in-game, which you can do by clicking their highlighted name when it appears in the story! If you've never unlocked them, they won't show up!
