Srry if this is disturbing buttttt
Here's some info on each stage and what not of the whole emotional suppressant thing.
Because Sigma is a technician and executioner in the Genosys Project, emotions are not necessary. He signed up for the program long ago, in order to eliminate his ability to feel emotion. Because simply removing emotion surgically is still too dangerous, a device called the "Suppressor" is implemented into the trainee. In this way, if the trainee begins to receive emotional signals from the body, a horrible, pain-inducing serum is injected into the body. This prompts the trainee to avoid emotions and move toward total apathy. Sigma's training is 5 years in the making. It is estimated that within the year, he'll be completely apathetic, even without the use of the device.
serenity, joy, ecstasy, acceptance, trust, admiration, terror, fear, apprehension, amazement, surprise, distraction, grief, sadness, pensiveness, love (See Plutchik's Wheel of Emotion)
No emotion whatsoever. Interest is allowed, and some other emotions necessary to carry out his line of work. No pain serum needed.
Illegal emotions detected. These can range from mild, to strong, and the serum is injected further into the system depending upon how many emotions are detected. The way it works is that there are circuits connected under his skin that lead into his brain and his ear where the device is connected. This prevents him from removing the device without totally killing himself. The circuits are only present in his face, and are connected to his nerves. When the serum, which is an electric blue, reaches the nerves, well... You can guess what happens. It's a little more than horribly painful.
STAGE 3- (LOOPING)
Emotional shock and emotional looping are what occur here. This is seen most often in new trainees. An emotion is felt, like happiness, then the pain sets in. Fear of the pain occurs, which is also an illegal emotion, leading to more pain. The pain then increases, leading to sadness and more fear, which in turn, continues to increase the pain on a loop. This is called "emotional looping." The serum heats up and becomes a bright, boiling red if this occurs for a long time. Emotional looping can kill a trainee, or drive them to kill themselves, because of the intensity of the pain. See Sigma crying up there? Sigma doesn't cry. That doesn't happen naturally. That serum freaking hurts.
The only way to calm emotional looping is to smoke. No, not regular cigarettes- electronic cigarettes. I'll get some refs up soon, but essentially... It's a regular cigarette with glowy electric blue bits on the end, and it emits vapors that numb the emotions enough to calm an episode. It's horribly detrimental to the body, though- it's recommended they are only used in case of emergencies such as that one. Sigma smokes them a little too often, though.
There is a fourth stage for Sigma. I'll reveal it after I actually make the game, of course. It's sort of a big plot thing. I guess.
Thanks for reading, and may the suffering continue.
