My biggest mistake? Surprisingly, I'm not gonna say it was the TRE merger; I'm gonna say it was not pursuing our enemies when we had them weakened. We let up when we should have continued pushing - that allowed them to regroup.
As for Parrot...Trusting her was probably mistake #2. I've heard her voice - it is definitely that of a 40+ year old, at minimum, with years of cigarette smoking. I suppose it could be a 30+ while eating cigarettes. I've heard about her "engagement," and have also heard that it was ended when she would not meet with the guy IRL; or, at least, that it was ended when she turned out to be a 40 year old woman. There was a lot of drama that crossed as far back as W2, where she caused a major schism in her tribe HOT. That mess about her mom getting sick and dying? Almost certainly a lie.
However, DTA: So really, I caught you red-handed in trying to break up the tribe, after all? Interesting...
