As they wander through the Fortress's opposite, they see that the place has been festively decorated with hundreds of human skulls. Some sit atop pikes, others dangle from garlands. All are marked with Omegas. "It's a warning from the Zoners," Clark explains. "Consider it a not-so-friendly 'keep out' sign." Is there such a thing as a friendly "keep out" sign? It's all relative, I guess. Also, the trip has done absolutely fantastic things for Clark's hair. It's all curly and tousled and... not dorky. He looks years younger. They realize Darkseid has been there and may have been responsible for sending Slade back to Earth. Oliver's a bit unimpressed. "When you said Jor-El built a prison, I pictured something a little more confined than a national park." What kind of national parks are you going to? Clark explains that "Krypton's worst criminals could have some kind of life" there. "Seems like a real sweetheart," Oliver says under his breath. They make their way to the gateway, which is also bedecked with an assortment of skulls. Clark buzzes his little watch thing to let Watchtower know what's going on. Before they can get to the portal, they hear an eerie shriek in the distance. "Phantoms," Clark says. "They're the most dangerous prisoners here; we need to hurry." They reach the console, which is made of the same black crystal as the rest of the place and stamped with a big S-shield. The middle of the shield has a conspicuous empty spot. "Someone took the crystal," Clark says. Oliver's not quite grasping the urgency of the situation, so Clark explains that the crystal itself is the gate. "Whoever sent Slade back must have taken it with them." Maybe before they came all this way, they should have checked Slade to see if he had it. He doesn't, of course, but they didn't know that. Clark and Oliver ready themselves for battle. A phantom swoops in, black and ragged like a Hefty bag full of leaves that's been left outside too long, and devours the screen whole.
