Dr. Grey turned herself in during the Season 15 finale. She got an excellent lawyer, who worked out a deal that she would just have to complete her community service hours and attend a court hearing. But, Meredith left her community service early one day when she had to speak to Dr. Bailey about the scathing article Meredith wrote about Grey Sloan Memorial.
Then, when her court date arrived, Meredith’s daughter, Zola, had complications in conjunction with a spina bifida procedure she had years earlier. Meredith refused to leave her daughter’s bedside while she went into surgery, and she was given jail time as a result.
In the promo for the Oct. 31 episode, which is aptly centered around Halloween, Meredith is concerned that she won’t be back in time to trick-or-treat with her three kids.
