Well. That's a lot to take in. Did Sentinel kill Rose?! What idiot decided to elect Lex "Tried to destroy the planet more than once" Luthor as president?! Where in Rao's name is the Justice League?! Find out next time on Dragonball Z!

I implied that Sentinel was responsible for Rose's death, but she would have been a zombie at the time. If you'd like it not to be Sentinel, then she was caught in a fire of some kind.
