3x01: Annie’s room 4x02: the attic 5x02: the attic
The chair’s journey to the attic (from 4x08): Alex: “What’s the biggest thing you’ve ever rentaghosted with?” Annie: “Hey, listen. This is not a party trick. This is an invaluable defensive weapon.” Alex: [raises eyebrows] Annie: “An armchair.”
#so Annie rent-a-ghosted the armchair to the attic by herself #she decided to get rid of the armchair once the others had left the house #okay I need a moment #because poor Annie got rid of the only thing she had that reminded her of the pink house #and so of the one she loved #I’m pretty sure she’s also the one who kept Mitchell’s gloves #and she hid them in the attic too #there but not quite there
Annie wasn’t getting rid of the chair. She brought it to the attic because she was spending a lot of time there taking care of Eve. She’s shown feeding Eve while sitting in the chair in 4x04.
