I have had a look through
Boro’s posts – there were more than I thought!
As has been noted, he talked a lot about Bear tactics and Bear v Wolf dynamics. Probably more so than anyone else, so perhaps he
was attacked because the Wolves had spotted him. If so, he only has himself to blame, as that was his advice to them.

However, we cannot be sure that they did, so it is worth looking to see whether they might have had some other reason for attacking him.
At various points, he expressed suspicion to varying degrees about a fair few people. This figures, I suppose, as he would want to keep his options open. Other than
Morsul, however, his main suspect appears to have been
sally (#101 and #131), although he wavered to and fro on
Nogrod and
Greenie a bit (#131, #135 and #164) and noted right at the end that he was tempted to vote for
Lari but would check her out the next Day (#166). I think that, if the Wolves did target
Boro because of something that he said about one of them, then this would point towards
sally, and perhaps
Lari, more than anyone else. Which is interesting, given that they are the two
Hakon voters, and I think one of them is quite likely a Wolf. But it’s a fairly tenuous lead, and I didn’t see much else in what he said that might have provoked the Wolves to attack him.
