Not just “THE queen...”
Jon calls Daenerys her “MY queen.”
If you don’t get the multiple connotations of that, I don’t know what to tell you.
Dany is destined to be Jon’s queen, his wife, and the mother of his child.
In turn, Jon will soon be Dany’s king, as well as her husband and father of her child.
I love my babies. Loved them each separately, but oh, how I love them together.
(Love them, do you hear me?! LOVE.)
