Poisonous Presumption (слэш)

This was the worst assignment Davies has ever been given.
 
Sure, it sounded easy upfront – infiltrate the Avengers medical staff and use his access to find weaknesses and sabotage medical treatments – however, it was proving to be anything but. Davies did have medical training and experience, which was part of why Hydra had picked him for this assignment, but the task itself was… complicated.
 
When Tony Stark winds up in Avengers medical, an undercover Hydra agent sees the opportunity of a lifetime. It should be easy to tip the balance and send Iron Man into the waiting jaws of death... so why won't he die?
