Out of all the characters in your au, who do you think will have the most trauma once the infection is finally cured?
100% Buttercup, even after her main arc, she loses so many influential people in her life during the final arc and with everyone in the cast retaining their memories after the infection is cured, she still has horrible night terrors and Utonium has her in therapy twice a week
I can also concur that Finn and Zak are pretty traumatized too, Finn is on his tiptoes throughout the entire story with Jake being infected (with the possibility of dying at any moment), and he still has to be constantly reassured that the infection is gone for good and Jake is still there. Zak practically lost most of his friends, witnessed two of his closest companions deaths, and on top of all that can communicate with the infected thanks to Kur. Their pain still took a heavy hit on his psyche.
Ben and Dexter are also in a similar situation to Finn, they constantly wake up in fight or flight thinking CN-DS being cured was just a dream and that they never got their families back
