In issue #4, Batman corrects the statement that the death of Flash and the capture of Green Lantern can be simply described as "tough", suggesting some care for his teammates.
After his resurrection, Flash insists that he immediately rush off to rescue the rest of the League, a mission where it's been proven death is a real possibility. His reason is that he has to save his "friends".
When Ariel Masters meets Green Lantern, he is the only hero who actually impresses her. She outright states that he is everything that the legends promise.
In the aftermath of the battle against the Legion of Death -narrated in Justice League 3001 #12 and Blue Beetle (Vol 10) #13-, The Flash wonders how they may possibly triumph over Lady Styx. In reply, Supergirl embraces and reassures her:
Flash: We may have won this battle— but there's still a helluva long war ahead. Supergirl: And we'll win the war, Teri. I know it— in the bottom of my soul. Flash: How can you know it? Supergirl: Because in the end, hope will always win out over despair. And simple human decency will always triumph over evil.
