The battery part was durring exposition, that is where you explain weird concepts! Then why also continue with that shit excuse in the latest fucking movie. They had the chance in no. 4, they basically had a blank canvas, explain the retcon in one of the many scenes they had to explain strawberries. No they made their choice, back in the first movie, and they kept doubling down. Batteries, even though it makes no fucking sense, they made their bed. PS love the Wachowskis, I still appreciate all they have done to entertain us
