Summary: [Tag to Season 3's "The Deadly Smorgasbord Affair"]. Illya returns from his solo mission and is not pleased with what he hears went on in his absence.
I've been sitting on this fic idea for years--since I saw the episode "The Deadly Smorgasbord Affair" in 2016 and realized that Waverly kinda did overstep his authority by approving an experimental treatment on Napoleon and the innocents, especially when there was no guarantee of their survival. I certainly think Illya would've called him out on it afterwards, as he had not been present when it all happened, so this fic happened.
