Yeah, but if it takes even just a week or so for her to sail to and back from King’s Landing, that’s still really stupid since a lot could happen in that week which would require the Queen’s attention, and her council would be unable to contact her. I guess should could have just used her dragon to fly to close to KL (but not close enough to be seen by the Greens) in just a few hours, and then take a few hours to travel by horse to KL?
