Game of Thrones relationships are complicated as this diagram proves. Spoilers ahead.

“The Winds of Winter” finally took us inside the Tower of Joy. Here's a brief recap of what brought Ned there:

The only daughter of Rickard Stark, Lord of Winterfell, Lyanna Stark was engaged to marry Robert Baratheon. According to Littlefinger, eyebrows were raised at a tourney hosted at Harrenhal when Prince Rhaegar Targaryen rode past his own wife, Princess Elia Martell, and presented his winner's crown of winter roses to Lyanna instead.

Sometime after, news spread that Rhaegar had abducted Lyanna. When her brother Ned made his way to Dorne and found the Tower of Joy, he discovered his sister, Lyanna, drenched in blood and sweat on a bed. “Promise me, Ned,” she whispered as a brown-eyed newborn was placed into her brother’s arms.
