Synopsis:
Lana Lang sees Clark Kent defacing Superboy posters around Smallville. She suspects that Clark has become jealous of Superboy because she likes him more. Lana tries to question Clark about the vandalism, but he runs off. Later when an earthquake knocks out power, Clark's acts of vandalism glow from luminous paint. The light is visible for aircraft to use as guide markers to find the airport. Lana believes Superboy asked Clark to secretly make the guide markers. Clark was really just protecting his secret identity by covering up parts of the posters which would have revealed his secret.
