Since Meredith Grey relocated to Boston in Season 19, her presence at Grey Sloan Memorial Hospital has shifted from daily lead to a more distant, albeit still influential, figure. While she maintains a connection to the hospital's overarching storylines, particularly through her opposition to the new chief's focus on VIP healthcare, her everyday involvement in the lives of the residents and attendings has significantly decreased. This change has naturally led viewers and critics alike to ponder who might step into her shoes as the emotional and narrative anchor of the series.

Season 23, Episode 3, offered a compelling answer, focusing heavily on Dr. Jo Wilson and Dr. Simone Griffith. Both characters have long been recognized for their challenging personal histories and professional struggles, drawing parallels to Meredith's own tumultuous past. The episode brought their individual journeys into sharp relief, showcasing how their experiences mirror the resilience that defined Meredith Grey.

Simone Griffith's backstory, introduced in Season 18, immediately resonated with Meredith's narrative. Her traumatic connection to Grey Sloan Memorial, where her mother died during childbirth, set a precedent for a character grappling with profound loss within the hospital's walls. Further developing these parallels, Simone has navigated her grandmother's Alzheimer's diagnosis and her relationship with Lucas, which many viewers note echoes the early dynamics of Meredith and Derek.

Similarly, Jo Wilson's arduous family history and the trials she endured during her residency at Grey Sloan have consistently highlighted her affinity with Meredith. Jo's consideration of quitting OBGYN and even medicine altogether, while not identical to Meredith's temporary escape from Seattle after Derek's death, reflects a similar inclination to flee overwhelming adversity. Both characters have faced seemingly insurmountable challenges, only to find ways to persevere.

The recent episode cemented these comparisons through a shared storyline. Simone's molar pregnancy and her intense fear of anesthesia, stemming from her mother's tragic delivery, forced her to confront deep-seated trauma. It was Jo who performed the D&C procedure, creating a pivotal moment where both doctors had to face their fears head-on. This shared experience not only underscored their individual strengths but also demonstrated their collective ability to embody Meredith's enduring qualities: confronting adversity, finding inner strength, and continuing to fight.

While Jo and Simone's breakthroughs in Season 23 are significant, Screen Rant suggests that their development as Meredith's successors could be further enriched by Meredith's direct involvement. Currently, Meredith's intermittent visits to Grey Sloan primarily revolve around her Alzheimer's research or her principled stand against the hospital's new VIP patient focus. However, given her history of mentoring younger doctors and her unparalleled experience in overcoming unimaginable hardships, there's a strong argument for her to actively guide Jo and Simone. By offering her support and wisdom during her visits, Meredith could seamlessly transition into a mentorship role, solidifying Jo and Simone's positions as the new heart of Grey Sloan Memorial and ensuring that the legacy of resilience continues to define Grey's Anatomy for seasons to come.
