This chapter of our spoiler free walkthrough for The Last of Us 2 has a flashback, but this time you play as Abby who is taking tracking lessons.
Search for father
Move forward and try to find Abby's father. Enter the building next to the fence. Inside, a rat will knock a bucket and a bottle will fall out of it. Pick it up and aim at the window at the top - break it and go outside through it.
Now move the container up against the wall and jump on top of it. Jump to the other side and then go down - head to towards the park.
After the cut-scene, follow the protagonist's father, who tracks down an animal. When you get to the place where, as Abby, you're supposed to find a trace, approach the dead fetus lying on ground. Then go after Jerry.
You will come across a zebra tangled in barbed wire. After the cut-scenes, you will be moved to the hospital. Run to the red door to end this flashback sequence.
