Game Of Thrones Season 6: 8 Things You Need To Know About Tower Of Joy
2. Why It's Important
The Tower of Joy is one of the most intriguing and mysterious events to have happened relatively recently in Westeros, and that alone makes it compelling to see more of it. With the bloody fight, legendary figures, and return Ned Stark, it'd be a great scene to see without any extra meaning.
However, it's those mysteries that make it important. Or rather, the role it plays in one of the show's biggest mysteries: the parentage of Jon Snow.
The Tower of Joy is the glue that holds the entire R+L=J theory together. It explains Ned's promises, and why keeping them has cost him so much, especially when he thinks: "He had lived lies for fourteen years, yet they still haunted him at night."
14 is, at this point, roughly the age of Jon Snow in the books. Then there's the bed of blood, with childbirth being a logical explanation, and the presence of the Kingsguard - why else would they be there, if not to protect royal blood?
The evidence in support of the theory is almost overwhelming, to the point where it's basically a plot point we're just waiting to be officially confirmed. The Tower of Joy holds the key to that confirmation, and Jon Snow being the son of Lyanna Stark and Rhaegar Targaryen.
