Didn't Kit say Jon was going to listen to Sansa a lot more this season? Well how is he supposed to do that when he's traveling so much. Maybe it's a red herring and they actually do spend some time together this season. Here's to hoping!
I’m fairly certain they will be spending time together. Even the leaks confirmed scenes with them until Jon leaves at the end of episode 2. If the leaks are indeed true, likely Sansa gives Jon advice for his time away.
Perhaps she was the one who told him he should go in person anyway. Jon going to meet with a potential ally (who also wants to rule you) has obvious parallels to Cat going to meet with Renly in s2/ACOK. Renly said Robb could call himself King it would just be a title, he would have to be loyal to the Iron Throne/King Renly. Cat was somewhat willing to concede total independence in order to save the lives of her daughters, even though Robb and his bannermen said that they would never again be ruled by the south. Robb didn’t go himself, but Cat urged him to, thinking Renly would see it as a sign of disrespect. The main reason Robb sent Cat instead of someone else was basically to get his mother out of his hair.
Jon going to Dragonstone is the direct opposite. Jon trusts Sansa to stay and manage Winterfell. She will rule in his stead. It’s kind of funny, really, that it ended up this way because Sansa actually would objectively be the better diplomat. She knows Tyrion and is on good terms with Theon post-rescue (whereas Jon wants to kill him). She also knows the south and Cersei (the enemy) much better. But Jon is the one who has to ask for help with the WW (and has actually fought them) and I doubt Sansa will go south ever again.
Anyway, all this to say… I genuinely think they do trust each other.
Possibly Jon leaves due to Tortured Incest Feels and wants some distance. We don’t know. That would make them most sense if Jonsa were to become A Thing. This would mean we would need some sort of Incident before he was to leave. Perhaps the Godswood scene? After all, Jon says you can’t lie in front of the Heart Tree.
There is also the possibility of letters. By possibility I mean almost certainly they will attempt to communicate in some way. This isn’t even shippy at all. She is ruling his kingdom, after all.
Anyway, if Jonsa WERE to become a thing, in my opinion it would make a lot of sense to NOT hype it. It would certainly become an OMG moment if our innocent heroic Starks made out or something. There is enough foreshadowing in the cinematography last season, and D&D do love their ‘OMG’ moments. See: Sansa’s rape, making Talisa pregnant and making Robb watch her die, etc. for examples of shocking things that didn’t happen in the books.
Only 20 days left!!!
