Okay, from what I can gather SOV apparently caught someone doing something naughty last night, but this naughtiness was stopped by "The Man of the Swan." Also mentions "the good doctor" to be another resident of the hatch.
From what I can tell Swan is the Hatch. So I'm guessing those are your bad guys, not me. Considering SOV turned on Lissarae for this day lynch, my assumption was she was the one he caught being bad, and hence is the "Man of the Swan." If I'm right in that Swan = Hatch, then "The Good Doctor" is another baddie from the Hatch.
And seriously, if you think I'm making this **** up, re-read it, it's too bat**** insane for me to make up. If I could quote the damn message I would, but that is a no-no, so I can't.
