So what exactly is the plan? (Spoilers for season finale)

I don't know what I missed, but it was a bit confusing.

-Byron had a change of heart and decided to redeem himself

-He tells his stooges to cut checks for everyone and work on antidotes

-His son and robot lady get in, robot lady tells him her work can help reverse the side effects

-robot lady and son are in cahoots now

-his son wants the product to continue while also working with robot lady who's going to work on an antidote?

-Byron told robot lady to spare no expenses which is what she always wanted, so why work with the son to betray Byron?

-I assume robot lady's plan is to kill the son as soon as byron is dead to assume control of the company, but what about the other son? Are we to believe Byron doesn't have a plan in case he dies?

-with how many connections they have, why rely on the four leads to kill Byron?

-wouldnt news that Byron wants to make it right for everyone get out thus making the two FBI agents want to do things the right way?

Not to mention other general questions I have not related to the finale.

Does the antidote work for all versions? The scientist was working using the purest form as base, so will it work for people who got it through sex like everyone of the lead four except Anthony Ramos?

What about the deformed people?

How exactly does pregnancy work in this universe? Connor mentioned Bella wouldn't get pregnant because she was going to get infected during that session of intercourse, but what about a non beautified male having sex with a beautified female?

If an 80yo woman gets beautified and "turns" into a 30yo woman, can she get pregnant?

The people who transform into kids, do they age normally?
