Sim, Barry tem a distinção única de ter estado no centro do paradoxo Flashpoint . Ele pode ser a única pessoa a lembrar em primeira mão o que aconteceu lá. Será que as memórias serão retidas (ou ele ainda vai querer lembrar) ainda tem que ser determinado.
A Wikipedia confirma isso em sua entrada do Flashpoint :
Traveling back in time, Barry merges with his earlier self during the attempt to stop Thawne. While traveling through time, Barry realizes he can see three different timelines — DC (New Earth), Vertigo (Earth-13), and WildStorm (Earth-50).
A mysterious hooded figure (later reveals to be a cursed immortal Pandora) tells him that the world was split into three to weaken them for an impending threat, and must now be reunited to combat it. The DC, Vertigo, and Wildstorm universes are then merged, creating a brand new DC Universe.
Barry then wakes up in a similar manner to the beginning of Flashpoint, also retaining all his memories from the alternate timeline.
Believing that everything is over, Barry remembers Thomas' letter and gives it to Bruce, who is still the Batman in this timeline. Bruce, deeply touched by his father's sacrifice to ensure his son's life, tears up after reading the letter and expresses gratitude to Barry for informing him of the events that transpired before the timeline was reset. (REF: Johns, Geoff (w). Flashpoint 5 (August 2011), DC Comics)
Sim, isso significa que Batman sabe que houve uma continuidade diferente desta. Ele tem provas da outra continuidade na forma da carta de Thomas Wayne. Poderiam as memórias ser recuperadas por magia, telepatia ou super-ciência? Nós simplesmente não sabemos. É provável que o Batman esteja considerando isso agora ...
