Dana and Kevin have a close relationship even though she leaves because both have traveled back in time and they understand each other.
Dana met Kevin when she was working as a temp in an auto parts store. He was about to quit his job because he had sold his first book. They hit it off, because they both loved writing, and fell in love.
No one else can possibly appreciate what Dana and Kevin have been through. Each time Dana travels back in time to save Rufus, they do not know what is going to happen next. When Kevin goes with her, things get even more complicated. She is a type of ghost from the future, with a modern black woman’s mindset. Yet in the past she is a slave.
Both in the past and in the present, Kevin and Dana grow very close. In the past, they are the only ones who understand how different this strange world is from their own. In the future, they are the only ones who understand how experiencing the past has changed them.
We didn’t seem to have to grow back into each other. The separations hadn’t been good for us, but they hadn’t hurt us much either. It was easy for us to be together, knowing we shared experiences no one else would believe. (“The Rope”, 2, p. 243)
They can’t really tell anyone what has happened to them. When they are gone, they are only gone a short time no matter how many days go by in the past. Yet they have to explain Dana’s injuries, and people suspect Kevin. Kevin also worries about Dana, because he knows she does not get to go back to the future unless her life is threatened.
The relationship between Kevin and Dana is the one sticking point Dana has. Kevin supports her and understands her, and whether they go back in time together or she goes alone, he is the only one who can appreciate what she has been through.
