Aaron Kelly (Battlestar Galactica)

Captain Aaron Kelly is a fictional character in the reimagined Battlestar Galactica TV program. He is played by Ty Olsson. The character has been part of the show since the beginning (the 2003 Miniseries). Captain Kelly is the landing signal officer (LSO) aboard the Battlestar Galactica. At the beginning of the second season, Captain Kelly was third in line of command, after then-Commander Adama and then-Colonel Tigh. The character of Aaron Kelly has no direct analog in the original Battlestar Galactica

Captain Kelly was first shown greeting then-Commander Adama in a corridor before the decommissioning ceremony for the Galactica. Later in the Miniseries, Kelly is shown collecting the dogtags of the fatalities of the Cylons' earlier nuclear attack on the Galactica.

Kelly became executive officer of Galactica after Adama was shot and fell comatose, as Tigh became commanding officer and commander of the fleet. In that capacity, Kelly strongly VOICED his opposition to Felix Gaeta's plans to network Galactica's computers together to find the rest of the fleet after the fleet jumped using out-of-date jump coordinates, resulting in Galactica ending up alone.

Kelly was shown performing his duties as LSO in the second-season episode "Final Cut". He is on duty when Louanne "Kat" Katraine panics and finds herself unable to safely land her Viper due to stimulant abuse. This episode was also the first to give the character's first name as Aaron.

Kelly was still serving aboard the Galactica when she jumped away from New Caprica to avoid the Cylon invasion fleet. He served in the CIC during the Battle of New Caprica, in which Galactica fought a holding action to allow the civilian population to escape from the Cylons. Two weeks before the trial of former President Gaius Baltar were set to start, Kelly assassinated his first public defender and attempted to kill his second lawyer twice. When then-Major Lee Adama uncovered the plot and confronted Kelly, disciplinary actions were taken against him.

He appears briefly in "The Oath", leading a fire team of rebel marines trying to PReVENT Baltar and President Roslin from escaping Galactica. It's revealed in the following episode "Blood on the Scales", that Kelly had been serving time in the brig for his previous actions and had been set free by Gaeta and Zarek's mutineers to serve alongside them. His loyalty to the mutineers quickly begins to waver however, and he is visibly shaken after Zarek orders the Quorum of Twelve to be executed. He later discovers Galen Tyrol trying to reach a weapon in the weapons locker. They begin to reminisce and he allows Tyrol to escape. When he learns that Adama is AbOUT to face a firing squad he begins to crack under the pressure. He is found by Lee Adama who interrogates him about where William Adama was being taken. Kelly joins Lee, Tigh and Sharon (Athena) in stopping the firing squad from executing Adama and joins them in retaking the ship.
