If you paid half as much attention to the show as you are trying to bring it down you would know Jon Snow was on a boat trying to rescue free folk from the army of the dead in Hardhome.
Seriously what are people like you expecting to see on this show ? We are in the final 2 seasons, obviously with all the stuff that is still going to happen the showmakers are not going to dedicate much screen time for seeing how Jon and Davos will travel to dragonstone and what mighty adventures they both will encounter or how Jon had an interesting talk about his nickname the onion knight and how thinking about onions on a boat made him a little seasick.
There are bigger things going on, for the story Jon needed to see Danny at Dragonstone, I love the fact they don't waste time on brining him there and just get on with the important stuff.
We have had our charcater development, we know who Jon Snow is, we know what drives him, we know who Danny is and what drives here and we know who Cersei is and what she wants. We don't need hours of screen time to build up these charcaters in non essential little side stories. It is end game time, the curtain is about the fall and the showmakers are now throwing everything together in the final showdown of game of thrones.
Just enjoy it, no ?
