A young man whose father was killed by Tina Greer decides to get his revenge on meteor freaks after accessing Chloe's Wall of Weird database. Among his targets is Lex Luthor. However, when the killer sees Clark using his powers to save Lex, he learns the kryptonian's weakness and shoots him with a kryptonite bullet. This was a good episode and you see Lana once again using the moves Lex taught her in the Season Two episode Precipice.
