I think Bro could have been saved. Why: Dave and Bro both had a copy of SBURB, but Dave ruined his and used Bro's copy (the one he got after their strife). So if Dave didn't spill aj on his copy, do you think Bro would have played and still be alive? (I told a friend this but she said,"Nah, Bro just would have done whatever the hell he wanted.")
Dave needed to lose his copy so that DD could steal it and eventually put it in the lotus time capsule which would send it back in time so that Jade could get the disks and play the game. So if Bro could have been saved, that’s not the way it would have happened.
