Summary: A week after the newly-elected British Prime Minister reveals himself as an alien bent on world domination, newly-minted SHIELD Agent Natasha Romanoff is sent to Budapest, where she's assigned to the Londoner medical student who can save them all. It'd be easier if Agent Sitwell wasn't breathing over her shoulder (and if Barton wasn't breathing over the other), but she can tolerate it, as long as they don't get in her way.
Notes: for marvel_bang. I will have more to say later, but right now I am far too dumbfounded that I actually managed to finish a big bang.
Thanks To: the mods of marvel_bang, for their smooth running of the comm, and their utmost patience
