- "The wise benefit from a second opinion."
- ―Jedi Fortune Cookie
In the sterile laboratories of Kamino, the ailing clone trooper Tup and his friend ARC Trooper Fives are quarantined for examination following Tup's shocking murder of a Jedi Master. With the help of medical droid AZI-3, Fives is determined to get to the bottom of Tup's condition and uncovers a secret buried deep within the Republic's cloning program.
Rex, Fives, and several other clones bring Tup to Tipoca City, where he is immediately whisked away by the Kaminoans. Rex is sent back to the battlefield, but Fives is forced to remain on Kamino under the belief that a virus may have caused Tup's breakdown and that Fives may also have it. Fives is quarantined to a room which has a window where he can see Tup being operated on. Fives is increasingly concerned at Tup's discomfort during the procedure, but his protests only lead the Kaminoans to block his view. Fives is then seen to by the droid AZI-3, who reveals to him that he will not be let out until Tup's condition is determined.
Tup's results come back negative for a virus, leading to much confusion. Suddenly, Tup awakes and blabbers about killing Jedi, making Shaak Ti wonder if this is a Separatist brainwashing plot. Nala Se and Shaak Ti continue debating on Tup's condition and arguing on who has more authority over the clones. Shaak Ti, wanting an atomic brain scan on Tup, goes to contacct the Jedi Temple, while Nala Se, wanting to terminate the clone and do an autopsy, heads to Prime Minister Lama Su. Meanwhile, AZI-3 returns to Fives' quarters, where he and the clone have an argument about whether clones should be known by their names or numbers.
Nala Se meets with Lama Su, where they talk about the real truth of Tup's condition: a premature activation of Protocol 66.
