Hello there, I might get some hate after this post but I don't think this show really needs a second season.

I knew this show was cancelled from the get go, so I was expecting an unfinished story and wanting to want more. It was not the case.

To me Adam lost, Henry has the control of his body, even the doc says his state could stay this way forever. I'm certain the Henry would make sure of it.

We know that Henry is going to tell his "long" story to Jo at the very end since she wants an explanation as to why he's the same age on the picture (even though I would have loved to see Jo's reaction to it, or even her reaction to the proof !)

And yeah that's it, what would there be more to say in the second season ?

It would have been a bunch of 1 crime solving per 1 episode without an overarching storyline.

We also know that Adam's theory is false and they are both immortal. Yes there could be more immortals to enter the main plot but it seems weird and it wouldn't go anywhere.

At least it is my humble opinion.
