One life; those who attempt to change this blaspheme God.
Two graves for the same body and two graves joined at the side. He isn't sure if Grace and Lady were the same person or not, but Lady did have something human inside her, and so he gave her a small marker, in the same graveyard as his father and sister's tombstones. After some thought, he gave Killer a marker next to Lady's, because she loved him and he gave his life for her and they were always together then, so it seems wrong to separate them now. Johnny pays his respects at the three graves lacking bodies every year.
It only took four to cause a tragedy that ended the lives of countless others: selfless Grace and their grief-stricken father and opportunistic Marlow and himself. Sometimes he's not sure what his role in the failed ritual was. Why didn't he have any Will? Was everything his fault? The mere thought is enough to keep him up some nights. Another thought which tugs at him: he spent five years dead, and often wonders who he would be had he lived those years. He said to Shania once, "if I hadn't died, I'd be your age," and she responded, "but you wouldn't know it, since we wouldn't have met," and he wondered if it was wrong that he was perfectly happy with where he was at that moment, by Shania's side, despite the circumstances that brought them together.
He once traveled with six companions. They all came from different walks of life; all had their own strengths and weaknesses. Together, the seven of them saved the world—and then, for the most part, they had settled back into the everyday hustle-and-bustle, not wanting their worlds to slip by them.
Eight weeks after the Gate was destroyed, Johnny declared his love to Shania at an ice cream parlor. Her response: "there's chocolate on your face." His subsequent attempt to slide beneath the table and cease living was brought to a halt when she admitted that she was fond of him.
It takes nine months for a new life to form. Ten seasons had come and gone since the Gate's fall when Shania first started to show. She had lounged on the detective agency's steps, eating a piece of watermelon under the glare of the summer sun. Johnny almost passed her with a hurried hello but stopped short when he noticed that her abdomen had rounded into a continuous arc, slightly pushing out the trim of her shorts. She looked up at him, grinned when he averted his eyes, then took another bite of watermelon and told him, ever-so-casually, that the spirits were saying it would be a girl. His reaction: "you're kidding me, aren't you?" But as the seasons change and all the leaves on the trees shrivel and fall away, her belly has continued to swell. Johnny can now touch her belly to feel their child kicking, and as he does he thinks he understands:
It's one life, to be cherished always, no matter how long or short it lasts.
