User blog comment:Rassilon of Old/Young Justice spoilers at Comic-Con 2012/@comment-5012837-20120818121742

i have a theory...well several theories, really...the whole reason bart came to the past was to fix neutron, meet and save barry, and fix the future. but it turns out that neutron is fine, but the future still sucks. so if he fixed the neutron part of his plan, what about grandpa barry? i feel like barry allen's death is inevitable. if barry were to die this season, it would give wally a reason to become flash, and bart could possibly the new kid flash...right? but bart's mission still isnt over and in the previews, we see him staring down at someone with some type of strange eyewear, i guess. plus he is on the young justice poster with something falling from space. and he probably knows exaccctly what it is. if someone sent me back 40 years in the past(1970s) with the information i know now, i would go on a mission to fix stuff, too.

and bart knew fully well that he was not coming back, and i dont think he could even if he wanted to. you see dc comics decided to not only kill off one allen speedster, but two. meaning that even if barry's life is saved, it could be bart's death that screws up the time line...or his death could save it.

but i am getting way too ahead of myself. if anyone has any input or notice anything i missed out or got wrong, you are appreciated.
