CB will not be having any of that.
There are two things, universes and timelines. Universes works like a compass. North = Day Break, West = Street Hound, East = Broken Soul, South = Ravaging Beast. There's one more instance of Masuo that is mentioned but will only appear in LSH Ted. He made two hops to come to this universe.
Now about timeline. I will explain 1-3 first. They happen if Masuo goes strays away from Ryoko's plan and does something that changes so many things.
1- Marrying Junsa, He stays in the past with her and began family with her. Kind of what happens in Ryoko's reality.
2-Marrying Hitomi. Two outcomes. First one you see right now. Second one where you actually marry her. That it yet to be added.
3-Marrying Misa. You make her your girlfriend out of pity since she liked your dad so much.

Reiko hits motorbike with her car and when he is in the hospital begs for him not say it was her who collided with him. He agrees and the two becomes a couple sometime later.
