Mrs. Sinclair, along with her husband and Lucas, attended Will's funeral.
Mrs. Sinclair, along with her family, were having breakfast one morning in November 1984. While reading the newspaper, Lucas asked his father what he would do if his mother was angry with him. Mrs. Sinclair asked her husband the same question. Mr. Sinclair told his son that he would apologize for whatever it was that he had done, and then he would buy her anything that she wanted. When Lucas asked what he would do if his mother was wrong, Mr. Sinclair joked that his wife was never wrong.
Lucas was in fact, without his father or his mother realizing it, stealthily asking his father for advice on how to apologize to a girl, as he wished to make up with his crush, Max Mayfield.
While trapped in the Russian Elevator, Erica informs Dustin Henderson, Robin Buckley and Steve Harrington that she was supposed to have a sleepover at her friend Tina’s house, and that if she's not home for her Uncle Jack's party the next day and her mom founds out why, she will find them and “slit their throats”.
