NSMS is not a Magpie, as someone would have had to claim receiving a second Shiny Thing to CC his position. I don't think either the Ravens or the Crows would even attempt that.
That being said, unfortunately the Ravens having a Shiny Thing only narrows NSMS down from not being the Magpie (meaning I am still up for eating a D4 lynch to keep good on my D3 intentions), but it does put him at a 1/2 shot of being a Crow,so I think we can leave him be for now and look elsewhere.
Namely, I think TMR should be our biggest suspect going forward, along with ItzNarcotic, who isn't even confirmed as not a Raven at this moment.
