Back to reality, Rattmann is lying on the floor, wounded by the Turrets, reaches out to his Companion Cube but loses consciousness.

Another flashback begins, involving Henry having a conversation with GLaDOS. During the conversation, she tells him she would like to perform a recreation of the Schrödinger's cat experiment during "Bring Your Cat to Work Day". She says that, added to the boxes and the cats, she needs a little neurotoxin. Harry, accepts, "as long as it's for science",

Doug regains consciousness, and his schizophrenia has returned. The Cube can talk again and asks about to which he admits it was just a hunch. The Cube then tells Doug to
