The Power Of The Parasite! An alien geographer reassembles the disintegrated atoms of the Parasite, who saps his energy and life. Then the Parasite goes after Superman, only absorbing a bit of his energy at a time to avoid an overload.
Supergirl's Super-Date! When Linda Danvers gets a computer date with fellow student Duane Todd, he appears to covertly exhibit super-powers, and quotes a phrase in the Kryptonian language. After a while, Supergirl is convinced that Duane is a Kryptonian like herself--almost. But, when she attempts to date him as Supergirl, he gives her the brush-off. And, when Linda falls through the ice of a lake while skating on it, Duane admits he was faking super-powers, and she has to grab on to a log she snuck up from the lake's bottom in order to float . Later, Duane admits that he thought she was Supergirl, tried to convince her he was a Kryptonian, and turned her down as Supergirl because he didn't want her, as Linda, to think he was fickle. Since he is convinced that Linda is not Supergirl, he tries the computer dating service again, and gets...well...a "plain" person, which might be putting it nicely.
