User blog comment:Itamar20112/Arrow 8x01 - A good episode, but kinda breaks the Arrowverse/@comment-25054842-20191017000402

Update: It was confirmed that Arrow showrunner actually consulted with the Flash writers before destroying Earth-2. So I guess The Flash is gonna address that in a future episode along with Harry and Jesse's fates. Still doesn't solve the Robert Queen plot hole though.
