The Flash Season 6 Review: 8 Ups & 2 Downs From 'Crisis On Infinite Earths, Part 3'
4. Hope Vs. Courage: Dawn Of Crisis
Continuing on from the previous episode, 'Crisis On Infinite Earths, Part Three' delved into the unique relationship between hope and courage, as Kara Danvers considered using the Book of Destiny to recreate Earth-38 and undo the damage that the Anti-Monitor had done, while Kate Kane found herself torn between allowing her friend to do that (and risk driving herself mad) or using Kryptonite to stop her.
It was important that Batwoman was never pushed to the point to have to do that as it allowed Kara to make the decision on her own. This ensured that Supergirl didn't lose sight of the bigger picture and prevented the Dark Knight from having to do something she'd probably end up regretting. Ironically, it also allowed each of them to highlight why they are the respective Paragons of hope and courage.
The Infinite Earths are in safe hands with these two (and the rest, of course).
