TBB has this really great thread right from the pilot about clones and inhibitor chips, where we start with our protagonists split apart by being resistant to the chips against the backdrop of the "programmed" Regs, except the one who struggles against it until Tarkin has it jacked up into "go murder them" mode-
And then Rex gives them this perspective of how impossible they are to fight, even he couldn't resist-
And then we see Howzer not only come around on what's right vs following orders but refusing to run, holding out hope for his squad to break free too and do what's right-
To Gregor who is just done and deserted-
To the whiplash of the s1 finale where we get Crosshair. No chip anymore, but I'm a soldier, I'm loyal, I follow orders, I made my decision where then in season 2...
The underground is growing, more are walking away.
We get the fucked around and finding out perspective as the clones around Crosshair "keep disappearing." Cody drops some cold truths on his way out the door. Perhaps made even colder by presumably not knowing that whatever haunts him (we know) wasn't truly his decision at all.
Mayday the last straw, he held out and kept serving but for what?
We open season 3 on "not every clone is your ally" with Omega, the hints of Emerie's plight. And the later e6 warning that some clones on Tantiss are still loyal to the Empire. But Rex is still compassionate- doesn't know what the shadow is but knows something has gone very wrong. He's killed his men but Rex wants to find a way to help him.
And then they do this wild thing where -
They drop the thread completely, the ones who are still loyal at this point are beyond hope, the ones who are brainwashed victims are so over the top that you'd forget they're clones at all if they hadn't shown the one lose his helmet, it takes Emerie realizing there's kids in the basement to have second thoughts about experiments and torture on prisoner clones, and the commandos never serve any deeper purpose.
