Thoughts on Harry’s expression in the ending scene.
(FYI: I post this because I want to reply to @classicchanteuse in my old post(what I got from watching KTGC for 3 times), but it’s too long so I decide to write a new one.)
For me I don’t think Harry wants or expects anything from Eggsy but his happiness. Seeing Eggsy being married maybe it reminds him of himself, who never been in love, never did things he wanted because of Kingsman rules. On the way to Cambodia(Poppy’s Land) Harry told Eggsy about his thought when he was shot that he had nothing left behind, if you notice his eye, he said he felt regret and he really did. He devoted himself to be the best Kingsman agent that he didn’t have a chance to live his life or achieve his dream(to be the lepidopterist) and after everything that happened, including his home and Kingsman HQ were destroyed, Merlin’s death and Eggsy’s wedding.
Harry Hart lost EVERYTHING.
He doesn’t have family, friend, partner, home, his butterflies collection. Not only he’s losing everything(I don’t count ‘Mr. Pickle Jr’ and Tequila), but he has to live with the memory of killing innocent people, everybody inside that church(in TSS), by his own hands without being able to control his own body.
Please remember that Harry Hart is a very soft hearted person, judging from how he was traumatized from shooting Mr. Pickle for his final test to the point that he had him stuffed at home(“Mr. Pickle reminds of that every time I take a shit”), he took care of Eggsy at first it’s because he blamed himself for his father’s death(“Can’t you see that everything I’ve done has been about trying to repay him?” - to Eggsy, in TSS / “Our journey began from the mistake that I made.” to Merlin, in TGC) and the pre-Kingsman-Harry Hart, the sweet innocent boy who told Eggsy to shoot him instead of a puppy.
The world is at peace(again), Tequila is cured, Ginger has become Whiskey, Eggsy is happy to live his life with the person he loves and we see his mom in the wedding, alive and well. Everybody gets what they want EXCEPT HARRY. He thought he’s dead, then he’s back, but everybody left him. He’s basically the only person who is going to live with suffering.
He’s good at hiding his soft spot, but his expression was shown like that because the writers wanted to show us his pain. The only one who suffered while everybody smiles, laughs, claps and celebrates. The only one who always in pain throughout this sequel, even when he hadn’t gotten his memory back, he had been tested so many times.
You know sometime people who survived wars had suffered more than people who died, in this case, it’s Harry.
