Reid sits alone in Garcia's lair, the monitors being the only current source of light on the room to let him see the Rubik's cube he's working through. Hotch had obviously found out he lied about being cleared to fly, so he ended up being ordered to stay behind with Garcia while the team went out in the field.

He sulks in his chair, pouty over being denied going into the field when he managed to do it just fine before Hotch realized his doctor didn't clear him.
