(Spoilers All) Do the Tyrells know about Sansa? Lady Olenna conspired with Littlefinger to assassinate Joffrey using Sansa as a means to deliver the poison to the wedding via the hairnet. During the ensuing chaos, Sansa disappears and hasn't been seen since, nor has Ser Dontos. I don't know if Lady Olenna knew of Dontos' status as Littlefinger's agent, but surely it's within her ability to deduce that Littlefinger spirited Sansa away during the chaos of the Purple Wedding. So is it safe to assume that Lady Olenna has a good idea of where Sansa Stark is, and, if so, might this be a card she plays somewhere down the line?
