Why does the Rot need to turn their heads around to control them? Stop being creepy for the sake of being creepy, Rot!
The Parliament admit to using all of their power to resurrect Alec in the hopes that he would become their Warrior King. But he refused and he kissed Abby when they told him not to. So now they're acting like spiteful parents telling their child, "We told you so!", and refusing to help him because he didn't do as they said. What a bunch of jerks! I can't wait until they're dead and out of Swamp Thing's life for good!
The love story of a Head of Lettuce and a Hardened Cocoon.
It works. And Alec Holland becomes the monster once again. But this time he did it on his terms and for his own reasons. And he won't have any stupid trees telling him what to do. He grows wings made of branches and leaves and flies off to make war with The Rot. And possibly save Abby as well. Or, you know, fight her to the death. Whatever.
