Basically this is the lore: Gigi is the most Experemented subject by Delilah, who also wants to see Gigi suffer. The thing around Gigi's neck is a shock collar and tracker. Delilah has the key to the wiring in her room so she can tweak some things. It's impossible to open the wire bits without hurting Gigi without the key. If you tear out all the wires then there will be no signal from the tracker and Gigi cannot be shocked. The worst thing though is Gigi is easy to minupalate though.
