#and in the scuffle Doll emerges (as Cyn's host) and destroys the patch

I wish grown-up Tessa was legit, especially since she seemingly acts so "out of character" between episodes 3 and 7. It shows just how much the destruction of Earth affected Tessa as a character. It's character development. Trauma changed her for the worse.

I imagine Tessa feels extreme guilt for her hand in what happened. She brought Cyn home, she gave her room to grow into the monster she is now, and near the end, even though she absolutely saw the warning signs, she was too stubborn, too eager in her vision of what Cyn could be that she became blind to what Cyn was. I can absolutely see a timeline where Tessa feels personally responsible for not only Cyn's rise to power, but for the utter destruction of her home and the death of her entire species. For all she knows, she is the last human in the entire universe (and thus the last human that will ever exist, humans are going to die with her and she knows it) and it's all her fault. She isn't worthy of being the last human to exist, at least in her eyes.

That is a mindset I can absolutely see driving Tessa to the dogged determination to kill Uzi that we see in episode 7. She's so desperate for redemption and to avenge humanity, to prove that she's worthy of being humanity's last torchbearer, that she's unwilling to accept any solution other than the complete destruction of any possible method Cyn could use to come back. Any less and she'll have proven herself to be the traitor of humanity that she already believes herself to be.

That's an absolutely heartbreaking turn for a character that was, before, so bright-eyed and optimistic, and I absolutely love it. That's the Tessa I wish we got.
