Okay. Some thoughts about this proposal.
Mainly, I'm pretty certain Robz is Resistance now. Remember that, if he's a Spy then Qvist is also a Spy. I don't think it's to the Spies' advantage to have more than one Spy on a mission (except mission 4): it runs the risk of having multiple Sabotage cards thrown, which will give the Resistance a ton of info. So, him proposing a team with himself and Qvist makes me think he's not a Spy.
Robz could be playing a very long con. I doubt it.
So, what to do about this team.
If it succeeds, we learn nothing concrete, and are one step closer to victory. Awesome.
I have a feeling that, if one of these three people is a Spy, they pretty much have to Sabotage. So it's a good thing we've got this KACEOY card.
So, if this mission fails with one Sabotage, ftl should probably check out someone's card. I suspect it should be Galzria, but maybe Qvist would be better.
If ftl investigates Galzria:
ftl reports that Galzria Sabotaged the mission: this means that AT LEAST one of ftl and Galzria is a Spy.
ftl reports that Galzria did not Sabotage the mission: this means that EITHER Qvist is a Spy and ftl is Resistance, or BOTH ftl and Galzria are Spies.
If ftl investigates Qvist:
ftl reports that Qvist Sabotaged the mission: this means that AT LEAST one of ftl and Qvist is a Spy
ftl reports that Qvist did not Sabotage the mission: we don't know anything for certain here. Robz and Qvist could be Spies and Galzria could be Resistance. Or Galzria could be a Spy and Robz and Qvist could be Resistance. Or Qvist and Galz could both be spies. Or ftl could just be lying! Yeah, investigating Qvist is the wrong move here.
Of course, the thing about this analysis is that Galzria's name could be replaced with any other.
Robz, why did you choose this particular team?
