Mrs. Anvil

Arabella Anvil, known as Mrs. Anvil, is the main antagonist in First Time Alone. She is provocative, imposing, rude, authoritative, pompous, and vain.

She is first seen with Karen greeting Anastasia at her front door. From the beginning, Mrs. Anvil is very imposing and requests Anastasia to host Karen for multiple hours even after knowing that Anastasia's parents weren't home to host Karen. After Anastasia agrees unwillingly, Mrs. Anvil pushes Karen into the door and waits outside to make sure Karen opens the door for her. Shortly after, she barges into the house to give Karen a twenty dollar bill saying it was for lunch even though it was extra money to buy party decor. When Anastasia attempts to push Karen out, Mrs. Anvil forces her back in and tells Anastasia to drop it. She then rushes out of the room never to see Anastasia again.

She makes her next and final appearance when encouraging Karen, Holly, and Jill to make mature and provocative poses for the camera. When Lonny, Karen's little sister, suggests that Karen looks ridiculous, Mrs. Anvil belittles her and tells the three girls to ignore Lonny completely.

She is portrayed by Tesia Bell.
