As they fend off fire, Obi-Wan tells Anakin Skywalker that he thinks there are not enough droids for them to capture the entire city and that this attack is just a distraction. He orders Anakin to go and protect the clone DNA chamber while he deals with Grievous.

99 brings Fives and Echo more ammo including grenades. During the battle, young cadets join the clone forces. 99 offers to show them a shortcut.

As General Grievous makes his way through the facility, Asajj Ventress shows off her skills by Force choking and stabbing an unfortunate clone trooper with her lightsaber. Grievous compliments her on her style.

Asajj scoffs at the idea that Grievous thinks they are equals. Grievous reminds her that he is the general in charge of the assault and she is just tagging along to recover the clone DNA. The Separatists hope the DNA might unlock new military possibilities to overcome the Republic.

Back in the barracks, the inexperienced cadets ask the clones and 99 what should do. The troopers tell the children that their training is in the blood, just like any other clone. This is their home, therefore this is their war. 99 offers to help them find the armory.

Shaak Ti, Lama Su and the clone troopers are under attack at the command center. Shaak Ti slices apart the invading aqua droids. With the droids spread thin, Shaak orders the troops to take offensive action.

Asajj has found the clone DNA chamber and secures a DNA sample. Anakin Skywalker catches up with Asajj at the DNA chamber to confront her.

99 leads the cadets and troopers to the armory which holds everything they need to fight the aqua droids. Under attack from battle droids, 99 tosses ammo to the clone troopers as they throw grenades at the droids. While hobbling off to get more grenades, 99 is shot down by a battle droid and dies.

Grievous and Obi-Wan duel with lightsabers on a landing platform which is soon crushed by a Trident unit causing both opponents to fall. While Grievous scurries to safety, Obi-Wan is again saved by the aiwha.

Asajj and Anakin continue their lightsaber duel outside on one of the platforms. Using the Force, Anakin snatches the DNA sample from Asajj, who finds herself quickly outnumbered by several angry clones. She jumps onto Grievous' fleeing escape pod and makes her getaway.

While the young cadets celebrate their victory, the older clone troopers mourn the loss of 99. Echo and Fives stand at attention when Clone Commander Rex and Cody commend them on their actions during battle, and are promoted to ARC troopers.
