Notes:
- Sarah Walker is sub-main in Parts 6 to 7 and should receive a strong plot arc.
- Cosima / Delphine and Bo / Lauren rise toward sub-main status because they can carry science, ethics, medicine, city identity, and moral pressure.
- Kate Beckett should be part of governance, council work, city management, internal justice, or security structure.
- Karen, Holly, Joyce, Lucas's mother, and Dustin's grandmother are secondary family-layer characters, important but not sub-main by default.
- Seth and Summer remain strong secondary as legacy-impact characters after death.
- Chuck can remain strong secondary unless the skeletons expand his independent arc.
