Old Fitz – a much younger Fitz – the engineer who had barely ever left the lab and didn’t have any relationships other than with his mother and lab partner, would have been terrified of the conversation they were now having, would probably have blanched at the thought that he and Jemma had been sleeping together and pretending to be married without ever knowing their true standing.
Now, this Fitz, the new one who could hold a real gun steady and fire it, and would kill to protect Jemma without ever losing sleep over it – well, he was still scared. But having her pulse in his hand brought air into his lungs, and the strange peacefulness of knowing that dying to protect her was nothing more than his most basic purpose. His life for hers, at the sound of a gun. In his head, it seemed just that simple.
Adult, canon-divergence. FitzSimmons have to go undercover as married gangsters – and obviously, this changes things… This FItz POV is intense, full of suppressed emotion and told out of sequence, which somehow works incredibly well.
