Scar

S2, E15: The colonial mining ship Majahual has been working round-the-clock for a month extracting essential metals from an asteroid. The fleet has moved on, leaving Galactica behind to guard the miners from persistent Cylon raids. Their deadliest foe is an enemy Raider nicknamed Scar, the combat-savvy reincarnation of countless Cylon warriors that boasts a growing list of human kills. Hiding out in the asteroid belt, Scar is a master of hit-and-run attacks that are decimating the war-weary Viper squadrons and forcing them to throw inexperienced replacement pilots into the fray. The shaken pilots, led by Capt. Lee "Apollo" Adama (Jamie Bamber), cover their distress at the mounting casualties with a hardboiled demeanor. But neither booze nor a lustful encounter with Lee can vanquish the demons haunting Kara "Starbuck" Thrace (Katee Sackhoff).
