Let's just start a new JSA series from their origin, seeing them develop and meet, etc. during WWII with no Trinity and not even answer what earth they're from until 12 issues into it. I can see a good series either way, as long as it's from the POV of the JSA. Maybe if they're on another earth we see that discovery from the Jay's POV rather than Barry's... I don't know. I just hope they don't muck it up...
