I'm new to doing anything in the forums so not sure if someone has already covered this, but is anybody else curious about the image flash of the Legion ring that appeared in the Speed Force when Barry was travelling to Earth 2? One could argue that it was simply another nod to Supergirl, as Superman has an identical one in the fortress on Earth 38, but maybe there's something bigger in play here? I mean, who says by the 31st century, that the Earths still remain separate? Maybe they merge at some point in the future, allowing whatever incarnation of the Legion that may appear in Supergirl to be the exact same incarnation to (hopefully) appear on any of the Earth 1 series, as it will all be one timeline after the merge? Thoughts?
