That basically sums up this scene, but if you're looking for more detail, here goes. Basically Grey Worm and Missandei, who have been flirting for what seems like an eternity, finally get it on. Missandei confronts Grey Worm before he leaves for war, asking why he has not come to say goodbye. He replies that she is his weakness, which sounds like an insult but is actually a compliment. They finally kiss, and then we get the best sex scene in the whole history of Game of Thrones, the first one entirely devoted to a woman's pleasure. It's a shame it took a eunuch for this to happen, but I'll take it!
