All-Star Superman Vol 1 2

In issue #2, Superman takes Lois to his Fortress of Solitude, where he seeks to help her adjust to the new information regarding his identity. A skeptical Lois becomes paranoid when accidentally exposed to certain alien chemicals. She believes that Superman is plotting to kill her. She recovers after attempting to kill Superman with a kryptonite laser that he kept on display in his armory. They discover that he is now immune to the effects of green kryptonite. Superman explains that Lois's paranoia is due to chemical exposure and presents Lois her birthday present: a supersuit and a chemical elixir that grants her powers like his for twenty four hours.
