With a loud thud, the crystal ashtray hits Melvin on the back of his head.
Although Katrina tries her best, she isn't able to exert much strength under the influence of the drug.
Instead of knocking Melvin out, she only pisses him off.
Melvin touches the bump on the back of his head. His face twisting in anger, he raises his hand and slaps Katrina's face. "Bitch! Don't be insolent! You're lucky that I'm interested in you! How dare you hit me?"
Melvin's strength is powerful. The force of his strike is a lot stronger than Sophie's slap.
Katrina is slanted to one side, with burning pain in her cheek and a hint of blood in her mouth. The force of the slap suddenly leaves her brain muddled. She becomes dizzy as she sees stars. She loses the ability to resist.
