Arthur "A.C." Curry (also known as Aquaman) has stopped keeping in touch with the Watchtower gang. He takes vigilante matters into his own hands, along with the help of his new super-wife Mera. Together, they set out to blow up what appear to be deep-water oil rigs but turn out to be secret government-run detention facilities for vigilantes. It seems really bad for the ocean to blow that crap up, but I'll delve into that and other senseless things in the full recap. When Clark tracks him down, A.C. enlists his help in checking out the other facilities, but then gets himself caught by General Slade, an anti-vigilante zealot.
Oliver decides to sign up with the government as part of the new Vigilante Registration Act in order to get some inside intel and protect his friends. When Lois finds out, she has a confab with Slade, during which she sneaks a look at some of the secret facility blueprints. Along the way, she also finds out that although Clark told her he's got jury duty, he's actually out doing superhero stuff without her. She works her way to A.C. and Mera's headquarters in Florida just in time to share her blueprints with Clark when he finds out A.C. has been captured. She and Clark also discuss their trust/protection/relationship issues and realize they should be more like A.C. and Mera, working together, side-by-side as equals. Clark and Mera head off to rescue A.C, but also find that Oliver's being held captive. Slade traps Clark in a Krypto-cage then sets the auto-destruct sequence, because he'd rather die than be saved by a vigilante. Just before the whole thing kabooms, Clark X-rays Slade and sees an omega symbol etched on his skull, marking him as one of Darkseid's weak-minded prey.
At the end, Clark finally fully brings Lois into the fold and shows her Watchtower. He also finally reveals to everyone the whole "darkness" plot that's threatening to take over Earth and how it's all tied in with the VRA and Godfrey and all that jazz. Also, Slade somehow survives the explosion, but it doesn't look like he's going to be his old self anymore. Stay tuned for all the details.
Previously on Smallville: Clark told Lois that he's super, thanks for asking!; Lois's daddy, General Sam Lane, was trying to get the Vigilante Registration Act passed in the Senate; Sam softened toward vigilantes when the Blur/Clark saved Lois's life; Rick Flag has all the super team members tagged so that the Suicide Squad could track them; Warp blew up anti-vigilante headquarters; Oliver Queen came out of the superhero closet; Arthur "Aquaman" Curry showed up to take off his shirt, swim around a bit and make the other bad actors on the show seem a little better by comparison.
Currently on Smallville: We join a military cabal in a dark, flag-festooned room somewhere inside Fort Ryan, Kansas. "Liberty, freedom, equality," says an older gentleman wearing the uniform of a U.S. Army general. As representatives from the other military branches listen, he goes on: "These are the values that we have been charged with defending." He is played by Michael Hogan, whom some may remember as Colonel Tigh on Battlestar Galactica, but who is also kind of giving me a John McCain vibe. He says that these principles are being threatened as never before. The other military bigwigs don't seem quite as fearful. "With all due respect, Slade," says a naval officer, "our troops have worked hard to secure this time of peace." Slade fears that people looking for someone to rescue them will look to the vigilantes as heroes. He compares them to Stalin, Hitler and Saddam Hussein, all viewed as saviors by their countrymen until they turned out to be tyrants. The Navy guy scoffs. Slade, who must have skipped breakfast judging by how hard he's chewing the scenery, says, "The trust of the American people doesn't live in the Oval Office anymore." That... surely can't have been precipitated by the arrival of the vigilantes. Or did Nixon not exist in the DC universe? Anyway, Slade shows them a board with pictures of the show's heroes, past and present. There are photos of Oliver, Kid Flash, Kara and Clark's burnt S, along with a pencil sketch of Dinah. The other pictures are just black silhouettes; I think one of them is Zatanna. A woman in Army dress joins them and tells them about the act of terrorism against that anti-vigilante office. Slade says that the President has put him in charge of the Vigilante Registration Act. Surprisingly, none of the vigilantes have signed up. He swears that's all about to change.
