I assure you, it was not a personal action. I had considered from the beginning to possibly betray the first team to recruit me (because it would make it much easier to then bring down one side and end as a winner). And Itachi knows this, and in fact I told Ysan that I had planned to do it on day1 after I had been recruited (I'm not sure if I did in the thread though).
It wasn't the sinking ship thing that forced me to betray you... as I told Ysan, the reason I didn't do it on that very first night was because I thought that I wouldn't have any protection after the betrayal (since she told me that both of Aphrodite's summons were gone, and I had no idea how the shield worked). If I had known off the bat the true nature of those things, I would have taken action much earlier and been able to do more damage.
Please do not take it personally. My earlier comment was in jest only, I promise. I am merely trying to expedite the quickest way to my own victory, and with the setup for this game (that I deject after 3 nights if not sacrificed to again) encouraging betrayal as the optimum strategy, I felt that it was by far the most logical action to take.
