- Professional burnout and desire to redefine her identity beyond Grey Sloan.
- Opportunity to rebuild her relationship with Owen and experience a new environment.
What Changed After Her Exit

Her narrative function—bridging trauma, found family, and surgical excellence—concludes, freeing narrative space for newer characters.
