Once you gain control of Abby, follow the path down until you go under a log, then take a right and head into the Gazebo to find an Artefact 81/117. Make your way into the building on the left and then throw a bottle at a small window, now crawl through and interact with the bin to find a Coin 1/32.
Note: Coins will replace Trading Cards for Abby’s portion of the story. Once you’ve found all 32 Coins, you’ll be rewarded with the Trophy, Numismatist.
Place the bin against the wall and climb up, now run along the roof and drop down to the right to view a scene.
After the scene, follow Dad until you see some tracks, inspect them by pressing [Triangle], then look to your left and show your Dad the blood on the floor. Now follow him through the fence and a cutscene will playout.
Finally, head down the corridor and go through the red door for another scene.
