You live your life in a series of moments; you're born, you grow up, you die. You live, you laugh, and you love. His life was filled with moments; moments spent exploring the different galaxies in the falcon with Chewie, moments spent joking around with Luke, moments spent loving Leia.
Those were the best moments. From the day they met, the moments he got to spend with her were his favorite; teasing her, holding her, kissing her. The day she accepted his marriage proposal is in his top 5 greatest moments, followed closely by the day that she told him they were expecting a child.
The day his child was born was the greatest moment of all. He remembers sitting behind Leia in bed, holding her as she pushed their child out of her body, nearly breaking both his hands in the process and calling him every terrible name in the book for putting her through all the pain. He remembers the sound of his child crying for the first time, mere seconds of being born. He remembers Leia collapsing against his chest, energy completely spent from giving birth, never looking so beautiful. But most of all, her remembers the moment when he first saw his child. Pink face screaming, small patch of dark brown hair on his head, body covered in blood and other bodily fluids that come from being born.
He was beautiful.
Han knew in that moment that no other time in his life would ever be so good.
In no other moment in his life will be as happy as he was then.
And he was right.
In this very moment, he was dying.
Betrayed by his own blood, by the other half of his heart, by his son. His Ben.
As he looked into his son's eyes, he felt the intense pain of the light saber ripping through him, slowly ripping him away from the world of the living.
He reached up and touched his son's face, one last moment with his boy, before falling off of the platform, down the impossiblly deep valley below.
It was then that he saw those moments again, the happiest moments from his life, and the people who made him the happiest.
Chewie. Luke. Leia. Ben.
And then there was nothing.
