Reinforcements have arrived, and they are wacky.
Missed part one? Check it out here. Long story short, how would the Saga change if Darth Vader suddenly died partway through? His subdermal implants that kept him bound to slavery were never removed or addressed again in canon, meaning they could potentially explode at any time. Or perhaps Vader could control them. . .
Think back to the last time you watched Episode I: The Phantom Menace. We aren’t here to talk about how much you liked or disliked it. It could be 1999, it could be ten minutes ago. I don’t care. Actually, I want to talk about a curious throwaway line. Anakin Skywalker and his mother Shmi are sitting at dinner, giving some insight to their guests Qui-Gon Jinn, Obi-Wan Kenobi, Jar Jar Binks, and Queen of Naboo, Padme Amidala, about life on Tatooine. A sandstorm rustles and wails outside, and then Anakin gives some insight into the cruel methods used to keep slaves in line. He mentions a transmitter inside his body (as well as all local slaves) that will detonate if the slave attempts to escape.
