This is Grace Clarksons room, The scientist have installed a small window on the door that they can slide open and the window shows heatwaves, so if Grace is invisible they can see shes in there through her body temperature.

It has a small twin sized bed with white blankets, a small wooden desk with a few books and sketch pads. There is a latge wooden wardrobe filled with the same white outfit over and over, Also there is a small bathroom through a small door. In Grace room they included a paint easel so maybe if she has a vision she will paint what she sees.
