After a long cut-scene, we take control of Sean again. Ring the doorbell by clicking on it. Do that twice. After that, the boys will enter the house. Look around a little while the grandparents are talking in another room (no need to eavesdrop on grandparents, they will get back to you soon!). Have a few dialogues and then the game will skip forward one week. Go down for breakfast - you can get dressed in the clothes lying next to the bed. You can also use the sink to clean up before going down. You are now ready for breakfast. Go down to the kitchen and move to the grandmother sitting at the table - choose "Join for breakfast".
You can remove flakes from the countertop in the kitchen, the book from the sofa in front of the TV and the board game from the table in the room next to the kitchen. You can also draw a sketch sitting on the couch.
Our current task is to ask Stephen for the key. Go towards the large TV, pass the aquarium on the right and enter the room on the right. Grandfather asks us to bring him the glue from the cabinet. Go there and click "Search". Time for another story-related choice: "Hide the secret" or "Tell the Truth".
Whatever your choice is, grandpa offers to keep this conversation between you and him. We get the key. Leave the room - you get a task from Claire to make the laundry. Call Daniel for help - he wants to play hide and seek. You find him (actually, he finds you) in the bathroom - approach the bathtub and interact with the curtain. While you are in the bathroom, take the "Dirty Linen" out of the laundry basket.
To do laundry, go down, left and go through the first entrance on the right. A "Light Switch" is on the right of the entrance - click LMB to "Switch On".
Go to the washing machine and press the "Wash" button.
Go outside the balcony door in the room with the TV. Go to the pantry shown in the screenshot.
Interact with it. Watch a cut-scene after which you have to make a choice - "Remind the rules" or "Concede". The brothers talk to each other for a while, then we move the next morning.
