Mindslave ideas.

[Motherfucker]

I'm assuming you're proposing a hypothetical scenario in which someone uses the limitations I proposed in order to discover weather someone is a mindslave to another or not...

If you manage to get the badguy and the mindslave restrained in such a way as that there is no possible way they can escape or bluff their way out of punching another guy than good going sherlock you've cracked the fucking case. Honestly if you have enough reason to suspect party A and party B are mindslaved to one and other and have them both in custody than they've obviously fucked up enough that there's probably already no doubt about them being traitors.

You know how else you can find a mindslave if you have them in custody? Take them down to medbay and dig the implant out youself.
