Below is a walkthrough on the All in the Family side quest in Dying Light 2 Stay Human. To obtain this quest, speak with the siblings arguing on the rooftop east of the Bazaar in Trinity near the Holy Trinity Metro.
Search the ground floor of the dark hollow for Theodore
Work your way to the Dark Hollow at night and enter through the door on the first floor. You’ll then need to crouch under the wall and crawl through the hole on the right. This will bring you to a room covered with UV glow sticks. In this room there will be a doorway where the top half is boarded. Crouch under it then head forward. Again crouch forward under the half boarded doorway to reach the kitchen. In the kitchen clear the enemies then open the door next to the fridge. Once you open the door you’ll find Theodore. Speak with him to complete the request. Please note that it is a chemical area so work quickly as time will be against you. If needed you can always return to the UV room to clear your immunity. In the room just past Theodore, there is an inhibitor. On the second level there is also a locked room with a whole bunch of treasure inside.
