I believe, I'm missing the last 3 of the trauma section. (Or is everybody's gallery random ?)
Everyone's gallery should be identical as far as the order of pictures.
As far as which ones you're missing (assuming it's the last three):
- Path C, tied to a certain choice like the one before.
- Path B, unmissable. Should have already unlocked if you'd gotten the 4th last of the gallery.
- Path A, unmissable.
