The four part plague storyline concludes in Superman 314 (Aug 77), in a story by Pasko, Swan and Adkins.
Superman gets the alien creature away from Jamie Lombard, as Amalak brings it out of its dormancy state, and it begins a monstrous rampage, tearing up a McTavish’s fast food restaurant.
Superman does manage to chain up the beast, and pursues Amalak, tracing him to the Justice League satellite, where the space pirate has already taken down the Flash and Green Lantern. Amalak uses the Key’s weapons, and even Amazo’s inert form against Superman, but really he could have picked a wiser spot for the battle. Superman defeats him by using Kanjar Ro’s paralysis inducing Gamma Gong.
Amalak tries to make Superman believe that he has caused Amalak to die by using the gong, but Superman does not fall for this. Amalak winds up dying at his own hands, having achieved nothing.
Between Nam-Ek’s healing horn and the removal of the alien creature causing the plague, the journalists get better. Having come so close to losing each other, both Lois and Clark seem primed to make a commitment to each other, and indeed, Clark proposes to her.
Lois accepts, on one condition. That Clark admit that he is Superman.
And Clark refuses. This infuriated me, even as a kid. Was he really planning to marry her but keep lying to her about his identity? It makes for a heart-breaking scene, but it’s impossible to believe that there is any future between Superman and Lois after this sequence.
