|Dr. Pamela Black|
|Played By||Carrie Genzel|
"The mice have been exhibiting violent tendencies."- Pamela Black
She informed Oliver that the lab mice on which she tested the drug began to show irrational and angry behavior. She warned Oliver to stop using it, but Oliver was unconcerned. Lex Luthor then paid her more than Oliver to continue the research, but she refused. Lex told her he couldn't let her do that. Oliver as well as Clark and Chloe later found Dr. Black's body amidst the ruins of her laboratory. Oliver speculated that Lex had her killed for her refusal. The Metropolis Police Department arrested some kid from the halfway house for her murder, though Clark suspected Lex was behind it.
