Deprogramming: Give Doc Samson a power action and choose another friendly character within 4 squares and line of fire. That character can't be affected by Outwit or Perplex until your next turn.

Psychological Trickery: Doc Samson can use Mind Control. When he does so, he modifies his attack value by +1, and after actions resolve he can use Outwit and Perplex targeting a character he hit with this use of Mind Control.

What happens if Doc Samson uses Deprogramming on a character that has already been targeted with Outwit or Perplex?
The affects would end immediately. Deprogramming protects the target against both the current affects of Outwit and Perplex and any future affects (until the beginning of Doc's next turn, at least).
