"When boys and girls of a certain age live in the same home, awkward situations can arise. Some times I have heard even brothers and sisters develop certain affections. And when those affections become common knowledge, well, that is an awkward situation, indeed, specially in a prominent family." ~ Petyr 2x01
can we talk about littlefinger and the realization he seemed to have? when he went to talk to jon down in the crypts, he seemed to try to make jon angry. mentioning ned, catelyn and the army of the vale. it didn't seemed to be working. now you know littlefinger is smart and would never let his plans actually show. but at that moment he mentioned his "love" for sansa, and somehow, this worked. it made jon furious to the point he chocked littlefinger like ned did once in s1. now it might seems to be a unnecessary scene. i mean, why would they make a scene between jon and petyr and make him mention sansa that way to jon and jon be so furious about that more than anything? did he suspect something for him to do it? let's not forget that theres a deleted scene where after leaving the crypts, jon tell ghost to watch and protect sansa for him.
petyr leaves the crypts minutes after jon in time to see the jonsa goodbye. then we have a close up on petyr's face(was that necessary as well??) it seems like he just had a realization after seeing them. a few eps later we have petyr mentioning an alliance between jonerys and how the gossips says she is quite beautiful. why would he mention about dany being beautiful to sansa? also it's interesting how no one in dragostone mentioned an alliance between them yet. now why would petyr again mention something like that without having suspicious thoughts? to warn sansa about jon giving the north?(we know petyr wanted her to have power over the north) but they already know jon "bent the knee". so why was it necessary for him to mention it to sansa and only him to mention it in s7? tbh petyr looked suspicious and might have tried to get some reaction from sansa by mentioning a possibility about jonerys the same way he tried to get a reaction from jon (which he did) by mentioning his "love" for sansa.
