Yes, the credit was due to BTSC discussions. He could have had his WinCon met earlier (USA and Russia were known to them after N1/D1), but he supported (and even proposed) actions in N2 that allowed the other two to achieve their own individual WinCon. Maurice did most of the powerplaying in both N1 and N2.
I'm pleased that you weren't willing to reward the "lets all do nothing strategy". I was a bit surprised to see both of baddies survive the final night.
But I think that this credit to Maurice is misplaced for the exact same reason. Maurice's only realistic opportunity to win was through individual wincon. If he chose to put the group ahead of himself, it seems pretty analogous to what Hirk did. He didn't focus sufficiently on winning. Even if he hadn't been lynched, his actions allowed his only allies to escape (guaranteeing his demise anyway).
