Despite a number of comics in the past which focused on The Flash and his moral conflicts while acting as the angel on Superman's shoulder, we haven't had any stories discussing Barry Allen's life outside of being The Flash in the Injustice universe. Brian Buccellato's script for this issue corrects this oversight and while more is hinted at than stated outright, what we see is heartbreaking. There's also an excellent fight scene between Superman and The Flash for those more concerned with action than emotion.
This action is once again ably illustrated by Tom Derenick and Rex Lokus. If pressed to pick a favorite creative team among the many wonderful artists to work on Injustice, they would probably be my choice for the best. Lokus always finds the perfect palettes to enhance Derenick's pencils and inks and it's always a good issue when they're at work on the art.
