**only read if you have seen 6x12, spoiler***
we did see that osvaldo ardiles (and i think:several other ex-CBI agents) got tortured and stabbed with a knife...this seems to be an act of revenge to me.
"Revenge for what?" popped into my head.....
well the recent and last case was the Red John case
then i had to think about that weird woman who helped red john and attacked patrick in the church with a KNIFE .she also had a weird scene leaving the place and just walking by the fbi unnoticed
maybe it was red johns latest fiancee, maybe its some sort of rebuilding the blake association...personally I think it's both
however it has to be someone who hates the ex-CBI for a reason.let me hear your thoughts
