- "Yoda spoke of another."
"The other he spoke of was your twin sister."
- ―Luke Skywalker and Obi-Wan Kenobi
Twins were two siblings born at the same time from the same parents. Luke Skywalker and Leia Organa were the twin children of Anakin Skywalker and Padmé Amidala. Other famous twins included Tiplar and Tiplee, two Mikkian Jedi Masters who fought in the Clone Wars. Technically speaking, a clone was also the twin of his or her template, since the two shared the exact same genetic pattern. As such, Boba Fett was both the adopted son and the twin of Jango Fett. Ciena Ree was the twin of Wynnet Ree, but the latter died a few hours after the birth of them both. Ciena Ree vowed to live for the both of them.
