Mind Control is the power that allows the user to exert their willpower over others, dominate them, and make them subservient. User takes hold of others thought process and manipulating them serve the user's own goals, making them do what the users commands. Those affected by the user's ability aren't turned into mindless drones, remaining the same except for the fact that they're acting in accordance to what the user wants, often without even realizing that they're are being manipulated by the user.
Sadie seemed to have a weak form of mind control that only worked on Finn (her boyfriend). It could be her power only worked on people she had a strong intimate relationship with or just Finn specifically, since she couldn't seem to use her power to control anyone else. Sadie used her power on Finn to the point where he could never leave the house due to constantly being controlled by her. Eventually, he managed to tie her up to their bed and gag her so she could not use the power on him.
Finn kept Sadie there for quite a long period of time, regularly talking to her, feeding her and helping her go to the bathroom. Eventually, Finn is discovered when Rudy moves into his flat and often hears him talking to what he believes is a talking dog. When leaving for community service one day, Other Rudy stays in the flat and breaks down the door to the bedroom where Sadie is being held captive. She escapes, but later returns and she and Finn attempt to repair their relationship.
- Sadie has been the only person to display this power.
