One of the things I appreciated most about The Golden Circle is that how they showed how completely devoted both Harry and Merlin are to Kingsman.
Merlin tells Eggsy that there is no time to cry, and I am certain that it’s a lesson he had to learn in the most painful of ways.
Harry has never been in love, has never had someone to care about, has given up something so vital to life, so he could be a better agent.
Merlin, in the end, is willing to lay down his life without hesitation for the sake of the mission, of Kingsman. Because he knows that it’s Eggsy and Harry, who will matter more in this one moment, and that’s that. And Harry, he knows it too, accepts it, because that is what they most likely always knew would happen to them in the end.
There are so many spy movies with so many dark sides, but I feel like the complete devotion to a greater cause and the loneliness and sacrifice it brings with it were addressed better in Kingsman than in most of them.
