Arrow: 10 Major Predictions For Season 5
7. Flashpoint Won't Change Too Much
In the comics, Flashpoint is a major event that shakes-up pretty much every corner of the DC universe. For a number of logistical reasons, it was a lot smaller and shorter on The Flash, but the legacy of it is still likely to be felt throughout the year.
However, The Flash isn't the only show in this universe, and Flashpoint will have some impact upon Arrow, Legends of Tomorrow, and likely Supergirl as well.
It's been said that Diggle in particular will be affected by it, so it's not clear how that'll work, but it's unlikely that Flashpoint will be too huge on Arrow: it has its own stories to tell that are very much separated from The Flash, and a section of its fanbase won't even watch the other show, so it can't go all in on it, and it'll instead likely provide just another subplot.
