One missed call

When the Government launched a nuke to end the Chitauri invasion, it was up to the Invincible Iron Man to save the day. Convinced that he was not going to make it back, he tried to call Pepper Potts to say his goodbyes, but she was too distracted by the news to answer. But what if she wasn't? This short one-shot covers my idea of that AU event. Rated for mild language.
