When Sansa said that comment about Rhaegar kidnapping and raping Lyanna, and then Littlefinger had that look, I can see where people would think it helped confirm R + L = J. I think it is actually foreshadowing Sansa having been kidnapped and potentially raped by Littlefinger. I think they had sex either right before she dyed her hair (while they were on a high with getting away with killing her aunt and he was teaching her how to pleasure to manipulate), OR he is planning on having sex with her in the future.
