Comment(s):
- Story continued from the last issue and continues in issue #13.
- The flashback shows the events surrounding Zatara's death as originally shown in Swamp Thing Vol. 2 #50 in the pre-Flashpoint universe, as it happened in the New 52 universe. Mento's appearance is quite different and since he has't shown up elsewhere at this point it cannot be determined whether or not this is indeed him.
