Gerbera/Madnug's final moments were just plain heartbreaking to watch. He tries to kill himself in order to revive the General. Captain manages to grab him before he falls and asks the mad Gundam to let him help him. Unfortunately, this mirrors Madnug's Start of Darkness, renforcing the Generals Brain Washing. Madnug shakes free of Captain and falls to his death.
Shute's brainwashing. What makes it even worse is how this is the first time Shute's resolve has been shaken to such a degree. The boy was literally in TEARS.
