Now, back to your reasoning. You claim her reasoning was a "just because", and that's why you voted her. You see, this is funny because the person who voted before you voted for Jolty and then used the reasoning of "just because" exactly. Why not pick them out? Why did you tag your vote onto Jolty specifically. Even the vote right beforehand had some made up reasoning about strawberries. Why not that one? As much as you want to say it, your whole vote came down to Jolty voting for Rayne.
Now, the question is why. I can see three reasonings. 1. You're mafia buddies. 2. You're bringing friendship into the game. 3. Your role requires you to specifically protect Rayne.
1. I could see it, however you're experienced enough to know that one random vote won't start anything. So I see this as unlikely.
2. Kind of hypocritical if true, seeing as you made that big stink about it before (granted, you were right to do so since that case was ridiculous). This seems the most likely.
3. I've only seen this role once around here, and it was my role as an independent. Possible, but unlikely.
Now for your final point. It wouldn't have mattered if she had said "just to get the ball rolling" or not. You would have seen that in the exact same light because she voted for Rayne. There was no way for anybody to have reasoning at that point. The people voted for hadn't even posted yet. It was a completely random vote that you blew out of proportion. Now we have a bandwagon on a new player who probably won't be back for a second game because she got attacked for doing nothing wrong.
So my vote remains, and this is equally as large a mistake as ever.
