Darth Vader sees Anakin Skywalker vs Obi-Wan Kenobi on Mustafar (Revenge of the Sith) where he remembers what happened to Anakin, while at the death place of his wife, Padme Amidala (Polis Massa where Obi-Wan helped her deliver Luke and Leia Skywalker, with Yoda and Bail Organa). This comic goes from Vader at Padme’s tomb on Naboo, to Polis Massa as he takes out the Amidalans.
