"...Gideon Prewett, it took five Death Eaters to kill him and his brother Fabian..."

"And then, to see them surrounded by all those other happy faces... Benjy Fenwick, who had been found in bits, and Gideon Prewett, who had died like a hero, and the Longbottoms, who had been tortured into madness... all waving happily out of the photograph forevermore, not knowing that they were doomed..."

Fabian Prewett doesn't seem to be in the photograph. This story started there.

 There was no peace to be found anymore, no warm bed, woman, or whiskey or any combination of the three that could ease the death and danger. But since they were the Prewett boys, they tried all of 'em anyhow.

Side by side and fighting back, the Prewett brothers fall.
