No way could long haired Kane be a submissive.
Exactly. And we're back to the potentially dangerous (in terms of the healthy and polite side of the discussion) topic of fanservice and the fact that there's no way Kane could be submissive in nature. And it's not just the hair, it's his entire past, which never once hinted at submissive tendencies in his behavior (because he didn't have any)..
Tess, being the smart woman she is, has of course tried to eliminate the conflict of opinion, recently stating that there will be personalized canon endings for both paths, Dom and Sub. And that seems to be it, the conflict is resolved but it's resolved in the future, and if you look at the past where it all started, the conflict still remains...
The transformation of an "ordinary" guy, confident in himself and his powers, into a submissive weakling (at the will of the player) still looks rather artificial...And it is explained, perhaps, only by the fact that this is a femdom-oriented game, and Tess did not explain to a conditional new player, why a couple-three points of "slave" mistakenly received by him at the beginning of the game may well throw such a player to the sub route, although he may not have intended to go there at all...
