I'm sorry. It's Time. This scene must be scene. Mera is beheaded by Wonder Woman, by Diana. Mera is brave to the very last. To her very last breath. Their is a brutal image of Wonder Woman holding up Mera's decapitated head at the end of this very short video-clip.. sorry.. real sorry.. from Flashpoint Paradox.
