re: Crackpot ASOIAF Theories SPOILERS

That's a great theory that I never thought about. It always seemed weird to me that Littlefinger was planning on Tyrion's death to get the marriage annulled; but bringing Tysha back into the picture makes a lot more sense, especially for Littlefinger. Although I think Littlefinger wants to eventually marry Sansa; kill HtH somehow and then marry "fragile" Sansa. But I think Sansa is going to thwart his plans somehow.
