It's more than clear that And Just Like That... (the Sex and the City reboot) is going to keep bringing up Samantha in an attempt to have Kim Cattrall return to the show in the future.
In the reboot, Samantha's absence is explained by saying she fell out with Carrie, Miranda, and Charlotte and then moved to London. Carrie says Samantha was hurt when she fired her as a publicist, which is what led to them falling out.
And this explanation is not in character for Samantha AT ALL. She would never end a friendship over something like that, and she was probably the most loyal, selfless, and nonjudgmental friend out of the four.
And the story of her absence in the reboot kinda paints Samantha as a bad, petty friend when in reality, Carrie, Miranda, and Charlotte were actually the ones who were awful friends to Samantha. And here's the evidence:
1.When Charlotte slut-shamed Samantha for sleeping with her brother.
2.When Carrie, Charlotte, and Miranda made offensive comments about Samantha dating a woman.
