Right I rewatched the fight scene between Texas , Carolina , The insurrectionist leader and C.T. Now as we all know Tex as an A.I so its understandable why she survived C.T + innie leaders attack. C.T died from a axe to the abdomen and a axe to the right shoulder !
Now onto my point ! Although we don't know how long the freelancer story is from Season 10. I would assume its not to far away. Now in Revelation I believe or Recreation. Donut is shot in the head (and at the time presumed dead) C.T was injured and I believe she bled out. I think from the length Donut was shot in the head for , he would have died too.
All in all C.T was one of my favourite characters and I just believe she should still be alive simmilar to Maine (Meta)
