It's a bit jarring when you have one storyline taking place in a space of days and another in a space of weeks/months, especially when the storyline intertwine as they did with Theon and his sister meeting with Danny this week.
Yara and Theon left the Iron Islands the same episode Dany left Vaes Dothrak. Do you think it only took a few days for Dany to travel ~1,000 miles to Meereen?
