Simone’s Grandma’s Alzheimer’s Was Very Important In Grey’s Anatomy Season 19 But Has Since Been Forgotten
What defined Simone’s story whenGrey’s Anatomyseason 19 introduced her was her mother dying giving birth to her at Grey Sloan Memorial and her grandmother being diagnosed with Alzheimer’s, which was especially impactful because she had been Simone’s mother figure her whole life, having barely met her mother. However,Grey’s Anatomysubsequently made Simone’s grandmother a more marginal figure.
The ever-present drama ofLucas and Simone’s relationship dominatedGrey’s Anatomyseason 21, making the need for a breakup extremely clear.

Grey’s Anatomyseason 19 undoubtedly set up Simone’s grandmother as an important part of her life. With season 21 focusing greatly on Simone’s personal and professional progress, it would make sense that Simone would share that part of her life, beyond Lucas, with her grandmother.
