It would be great if The Flash could incorporate this aspect of Bart’s background somehow.
Part of me still hopes that there’s a twist in store that reveals that Bart Allen has been living in the 30th century rather than the 21st century.
Eventually Bart’s metabolism was shocked back to normal levels, but because there was no danger in the environment he grew up in, Bart’s early superheroics in the real world often saw him taking action without thinking about the consequences first.
That would allow for his impulsiveness to be dealt with differently compared to Nora’s; in the comics, Bart aged more quickly due to a hyper-accelerated metabolism, so to ensure he didn’t suffer from mental health problems, he was raised in a virtual reality environment that kept pace with his sense of time.
