This is the first of the Wildfire-aftermath stories. It features Corsi, who along with Stevens, returns home and learns why her father has always been so biased against her joining Starfleet - because during the Cardassian war, Starfleet asked to install sensor equipment on his ship to spy on the Cardassians... What should have been a run of the mill-trade run turned into a standoff with Cardassians, and his brother, Corsi's uncle, had to pay for it.
This story deals with guilt, regret and prejudice (and of course, stupid mistakes which lead to tragedy). In the small-universe-syndrom one of the Starfleet operatives Aldo Corsi had to deal back then, was William Ross.
Corsi is doubting herself, because, while she was incapacitated, lots of her staff died on the daVinci, and Duffy had to make the ultimate sacrifice; and of course, Stevens just grieves for his best friend. Frankly, I'd have liked to see the focus more on Stevens instead of on Corsi, because I'd rather have seen a best friend deal with his very personal grief than stuck up, duty-bound Corsi deal with her professional regrets. I'm not saying that Corsi's grief doesn't come across as very real (and the background story about her father and uncle did touch me), but given the often stated relationship between Duffy and Stevens as best friends I think that not exploring that angle a wasted opportunity. There should have been more, even clichéd tears, whatever, but not just Stevens as a sidenote to shed some light on Corsi... especially not in this "aftermath"-situation.
