You just have to keep driving down the road. It's going to bend and curve and you'll speed up and slow down, but the road keeps going.
Someday, you do not know when, you will be driving down the road and someday, you do not now when, you will make a wrong tun. At the end of the road, when you're least expecting it, he (or indeed she) will be there.
As J.J. has said many times, when you start a series you want to have a destination. It's like driving a car, when you pull out of your garage and you head out driving down the road, you have a destination, okay?
