I think Poyser and Sky aren't scum/scum at least, Sky didn't wanna get voted and I presume it's for a role-related reason, like only getting to use her role if she didn't get voted once during the last phase or something. That itself is pretty null but if I'm right on that role spec, if Poyser and Sky were s/s I wouldn't expect him to just vote Sky for the fuck of it and ruin her role. In fact it could very well be that Poyser thought the same thing I did and went for the trolly looking "oh whoops, you didn't want this to happen right?" vote, like I don't think he ever elaborated on the vote either, literally just voted her for teh lulz. Could be wrong on that, will keep rereading.
