How to Convince Joey You're Part of the Protest in Life Is Strange: Reunion

Life Is Strange: Reunion has a missable achievement called 'Not a Rat' tied to a protest scene.

While playing as Chloe at the Snapping Turtle, find a burnt flyer fragment near the fireplace for the forum password.

Use Amanda's laptop after claiming to know the password to read the forum and then choose specific dialogue with Joey to gain his trust.

Convincing Joey unlocks the achievement and reveals where and when the protestors plan to meet.
