I’m a little late today, but Chapter 4 is up!
In this chapter, we’re returning to the original universe. For those keeping score at home, you’ll know this is “our” universe.
Note the difference in the date. The second universe is 100 years behind us, so while it is 1980 for Sam and Sarah, it is 2080 here.
If you’re just starting, chapter 1 is here. Each chapter links to the next one.

These are some serious time-traveling characters. Must be difficult for them to transition from one time and space to another.
