But while the Rhaegar-Lyanna relationship looked like an abduction, there's reason to believe that she went with him willingly, and that they were deeply in love. For starters, Rhaegar was admired by those in his orbit, including Barristan Selmy, who served the Targaryens. "Rhaegar never liked killing – he loved singing," Selmy tells Daenerys of her brother. Rhaegar's gentle nature is relayed by many, and in the books even Ned doesn't think of him as dangerous. There's even more evidence if you go looking, but long story short, it's pretty likely that Rhaegar and Lyanna's love was mutual.
Were Lyanna and Rhaegar married?
Unclear. The Targaryens were known to practice polygamy, and some fans even speculate that Rhaegar was able to annul his marriage to Elia and secretly wed Lyanna. There's no proof of any of this, but it does seem likely, if only to legitimize Jon's birth.
