Take Lois

Superwoman decided to search for her doppelgänger and take over her life. Flying from the Daily Planet roof, she looked back and saw a light on, when she investigated she was pleased to see the Lois Lane of this Earth was alone working on a story. She flew back to the roof and entered the building, dashing down the stairway to the floor that Lois was on. Then, in a gust of wind and a black blur, the cameras on the floor were all destroyed.

Lois, having heard the noise, turned and saw a silhouette of a woman. As the woman stepped forward, she revealed herself.
