What happens as a result of a social take out is highly situational.
The same could be said about any outcome of being Taken Out. Nevertheless, the loser needs to make a good faith and honest attempt to carry out the outcome as dictated by the winner, that's how Take Outs work. If the Merlin lost the conflict but did it on his own terms, then that was a Concession.
A lot of the time, you're not even in the stage where taken out would even apply.
Imagine a thug losing a social conflict, rather than just get humiliated until he loses, he just starts punching and shifts the conflict to a venue where the thug has the upper hand. One of the easiest ways to prevent any further social interaction on losing ground is for him to use his Fists vs Mr. Smart Mouth's physical defenses to put a sticky aspect and/or consequences on him like "Busted Lip" and tag it for social defense when needed. "What was that? I couldn't hear you through all that blood." <POW> "You spittin' out teeth now or what?"
You're assuming my social attacks are hostile and not something like a Rapport, Deceit, or Presence attack.
