Reilly
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Reilly is a Viper pilot assigned to Galactica. He is killed by Scar. His death is particularly gruesome, as Cally purportedly has to "hose out his cockpit" (Scar). He is said to have been a competent pilot, but easily spooked. A photo of his girlfriend (presumably dead, presumably having been taken pre-war) is a recurring topic of conversation during "Scar", as no one seems to be able to remember her name.
