Ahaha Ginshu isn't cool at all, I'm sorry... he's like the antithesis of cool.

I was wondering how to handle that myself! Options include:

• Akemi fucks off for a year and doesn't tell Jack anything, and Ginshu is extremely confused when some random violent asshole is like WTF AKEMI DO YOU EVEN CHECK YOUR VOICE MAIL?? Which leads to Ginshu wanting to find out what Jack knows about Akemi (because he thinks Akemi is dead).
  
• Akemi is unstable and unreliable as fuck, so Jack knows about the split personality business (but did not approve this plan) and they've had a falling out over it. Obviously this is the least conducive to Akemi not getting strangled, but luckily, he's harder to kill than he looks.
  
• Akemi tells Jack that it's all a plot to bring the Resistance under Jack's influence, even though Akemi is really just a crazy bitch who's playing 4D chess according to his own made-up rules. Jack can probably override Ginshu's personality and tell Akemi to hand over the Leithians.
