Karen Anvil

Karen Anvil is the main antihero in First Time Alone. She is seemingly sweet, but can be very cheeky and clever. She is Mrs. and Mr. Anvil's daughter and Lonny's older sister.

Karen is first seen with Mrs. Anvil when meeting Anastasia at her house. She joins Mrs. Anvil in belittling Anastasia for having parents who work weekends and then barges into Anastasia's home. She sarcastically apologizes to Anastasia during the next scene, calling her mother crazy.

Shortly after, when Mrs. Anvil leaves, Karen welcomes two of her friend and assistant, Holly to help her set up for the party. Although she shows gratitude towards Holly for coming, she belittles her soon after and pressures her into cancelling all of her appointments for that day.

Despite Anastasia's constant resistance, Karen welcomes Jill, another friend, to help set up for the party. Shortly after, she tapes Anastasia to a chair in her bedroom and leaves Anastasia helpless for almost three hours.

Karen's first appearance in costume is made when posing suggestively for Mrs. Anvil despite resistance from both her father and her little sister. Soon after, she welcomes her friends to enjoy the pink party.

Although the first part of her party goes as planned, the party is ruined soon after when Anastasia rips the party decor from the walls and stops the music. During this scene, Holly finally calls Karen out for her behavior and storms away. Anastasia then walks straight towards Karen and bashes her in front of the entire entourage.

Shortly after, Anastasia's parents arrive and confront Karen. They kick out all of the guests and tell Karen she should have thrown the party at her own home. At this moment, Karen stops pretending to be a strong, powerful woman and shows her emotionally-weak and vulnerable self. She then describes the situation which she is in and apologizes to Anastasia. After the confrontation, Anastasia invites Karen to come back. Karen gladly accepts the invitation and shakes hands with Anastasia.

She is portrayed by Imogen Cohen.
