The difference here is that I had literally no other option to go to. Yeti was my only hope to win, so there is utterly no reason for me to betray her. There were, however, situations where you could have betrayed her for North. If yeti went with you on n8 and didn't hook you but hooked TIK, you could have killed her using the north kill and then outvoted me during the lynches for the win. This was not a likely scenario; however it was entirely possible. If loyalty were not a factor, it was absolutely a better move to try to win with me than with you, as again, the win with me was certain, while there was room for failure going with you. The issue of loyalty, however, is what made that not happen.
