Chapter 15 - S2-E5
Other mistake: When the most recently mutated Nelvaanian tries to show Anakin how to free his tribe mates, the second Nelvaanian he rips the control harness from, suddenly has his implanted left arm blaster missing; instead his hand - which should have been amputated - appears.
Chapter 12 - S2-E2
Other mistake: When Anakin returns from the infiltration of the enemy city, he sits down and says 'Lunch'. But he moves his lips twice for a one-syllable word.
Chapter 17 - S2-E7
Other mistake: When the Clone Troopers dispatched to protect Anakin arrive on Yavin 4, Anakin addresses their leader as Sergeant. As stated in several sources, Clone Sergeants have green markings on their helmet and arm armor, but this one has the plain white armor of a regular Trooper.
Answer: Her date of birth is unrevealed. What little is known is that she was found as a child (precise age unknown) by a Jedi who crashlanded on her homeworld of Rattatak somewhere around 40BBY (precise year unknown). Realising her Force potential, he took her as his Padawan and trained her for some years, only to be cut down by a local warlord before he could finish, leaving her to seek vengeance on the warlords who had conspired against him, precipitating her fall to the Dark Side. It's difficult to determine her precise age from all this, but if we assume that she was ten when she was found, and that was in 40BBY, then Asajj would be 28 at the outbreak of the Clone Wars. So figure on anywhere in a range a few years either side of that.
