(Spoilers All) My Season 5 Sansa Theory
Littlefinger goes to KL to pick up fArya, who was being trained in his brothel without the viewers' knowledge, and have Tyrion's marriage to Sansa annuled. Sansa accompanies Littlefinger to Winterfell where he presents fArya to the Boltons. No one recognizes Sansa, expect Theon, whose survival will come as a surprise to Littlefinger. I suspect Sansa's "traumatic" scene comes as a result of the Boltons finding out that the Arya they're presented is fake and Littlefinger's companion is actually Sansa Stark.

We had that scene during the blackwater episode of Cersei telling Sansa how women can use their fun parts to take advantage of men so I think were gonna see Sansa go from innocent to mynx this season and the controversial scene will come from that
