Dr. Zed is definitely the man to cure these poor mutated bastards. Definitely.
Dr. Zed is confident he can cure the people infected by Hector. And if happens to impress Tannis along the way, well, that's just a bonus. ALl he needs to put the plan in motion is you to kill the infected and bring their viscera to him to study.
Horrifying super mutants. Bet you didn't see that coming. Unless you did.
