The Flash said, "Bruce, it's Louise. Louise is the key. You're right. You were always right about him ... I came too early? I came too early ... afraid of him! You must find us! "

The purpose of Flash's words is to tell Batman that Louise is the key person, because Flash is from the future. In The Future of the Unjust League: God on Earth, Superman degenerates into a dictator by killing his wife Louise by mistake, and he will do whatever it takes for "world peace".

So the Flash wants Batman to protect Louise and prevent Superman from falling because of Louise's death.
