Get What You Need From the House

After the opening cinematic, stop by the house to get what you need. The object you’re looking for is upstairs, in the shoebox on Joel’s bed but there are other items to look at for journal entries and some story background.

Journal Entry - The Owl

Interact with the owl mug in the kitchen and you’ll sketch it.

Journal Entry - The Guitar

Upstairs, in Joel’s workshop, interact with the guitar to do a quick sketch.

Artifact - Joel’s Watch

This is required to progress the story so you can't miss it but it’s located upstairs, in the shoebox on Joel’s bed. Once you’re done, head downstairs to meet Dina at the dinner table.
