I don't know quite how to explain this , but Ive done pretty much everything already , i've gotten the most recent versions and did pretty much all i could , for all i could .
But rex is simply not unlocked in the scanner thing , nor the gallery place , like i was never introduced to her .
maybe it's due to How i skipped the dialogues of her in the beginning cuz i was replaying the game ( It had crashed, but all was good )
And now she Just has the unlocked portrait of her in there , i cant interact at ALL .
Also , you can talk multiple times to the little girl for her to give you multiple Gold orbs
