clues to identity:
has killed
Hakon,
Brinniel,
Shasta and
Durelin
has not been lynched yet
Okay... based on this, I would say the bear is at least somewhat experienced player (since he's not got a nervous breakdown or revealed himself yet and whether purposefully or not, he has managed to kill two gifteds) who favours careful tactics (all the kills are rather trail-less except for
Durelin, who leads trails to half of the village). This might be crappy logic too, but I think a newer-player bear would sympathise with other newer players and would thus be unlikely to kill
Hakon on Night2 - likewise, an old-timer bear would sympathise with other old-timers and not kill anyone he has a long history with on Night2.
This profilisation gives me three names:
Form,
Mac and
Nerwen.
Nessa and
autume would probably have sympathised more with a fellow ww-novice, I'm not sure (no offense!) if
Mira or
Nienna would yet manage this smooth and effective game as lonely killers and
Sally would probably be considerably more jumpy if everybody else in this game was her enemy (

).
Form,
Mac or
Nerwen? It is easy for me to choose, because
Form has strcuk me as bearish since Day2.
Mac is a worthwhile option, but I'm not ready to go lynching him based on this, especially as
Form is still alive.
Nerwen doesn't seem too bearish because a bear would probably be more actively hunting wolves during the Days to look more innocent and to be rid of his arch eenemies before it's too late. Also, I believe that
Nerwen could have been a bit more surprising in her kill choices if she was the bear.
