Heroes in Crisis features some riveting mysteries, including those who snuffed out the heroes of Sanctuary, who gave Lois the videotaped confessionals, and why the Flash’s body is five years ahead of where it should be.

You might remember that Poison Ivy was confirmed as one of the characters killed in the Sanctuary massacre earlier in the series with a rose from Harley Quinn, but we discover here that that was not the end of everything.

The Trinity may have uncovered the true killer responsible for the deaths at Sanctuary, but the artificial intelligence that ran the institution is the one thing standing between them and the culprit. Now Batman, Superman and Wonder Woman must face off with their own creation—and face the consequences for what they created. Also, as the truth is uncovered, Booster and Harley go from being enemies to allies.

Like we mentioned above, Poison Ivy was previously confirmed by Harley to have been one of the characters killed at Sanctuary, and to memorialize her love for Ivy she threw a rose into the water. A hand grabbed that rose though and it turns out to be have been Wally West, who we see here alive and breathing…

He flourishes the rose and snaps a piece of the speed force into it, and as he narrates about a poem Linda used to read. Her new look isn’t really a costume, but is completely natural, giving her a much more organic look overall.
