Also, we now know one of two things.
Either
A) Radish was targeted and protected by the nurse
B) Radish was recruited
C) someone else was targeted by the killer was blocked.
D) mafia refrained from killing anyone for whatever reason
Those are really the only possible scenarios, in my opinion.
I would say D is really only something I would do as mafia. Everyone is too chicken to not kill, but it's a good tool in many situations.
C is also possible, though Radish SHOULD be their number 1 target, so it's more unlikely.
B is very possible. Oftentimes mafia have to forgo their kill in order to recruit.
An example would be vampire http://wiki.mafiascum.net/index.php?title=Vampire
and...shit the mikeburnsfire various roles page is down.
There was another one called like agent, or secret mafia, and the mafia didn't know who he was but could recruit him upon forgoing a kill.
The other thing is that if there is a busdriver, then spurge would have NOT hit radish, since if they wanted to kill radish, they would have bussed him. Both hat and nen swear up and down that a busdriver is me being insane, so I'm going to take it from people who would know better :D. This would mean that the simpler explanation of hat playing to be scanned is a godfather role, and maybe nen is just unkillable. Actually makes quite a bit of sense.
Therefore, I'm going to go slightly out on a limb and say hat is godfather, nen is deathproof, they targeted radish and he was protected.
The alternative is that they bussed Radish and recruited him so that he wouldn't be killed by the 'lightbringer'.
Or, they recruited him and simply bussed someone else?
I'm going with the first scenario. They targeted radish, were blocked thinking nobody would protect radish, hat is a godfather, nen is nightkill proof, and there is no busdriver. This is also supported by the fact that both nen and hat are looking at Radish for a lynch today. Other people who were considering it may also be suspects.
(other than that happy, go nuts :D )
Also, this is why we're leashing the SK, and why we are not trusting those who want to lynch him.
