Fan Casting Pamela Milton in HBO's The Walking Dead

She is the Governor of the Commonwealth and the mother of Sebastian Milton. Pamela collaborated with Rick Grimes until she mistakenly thought he had betrayed her, nearly causing bloodshed in the community. Rick managed to stop the bloodshed and eventually Pamela was stripped of her leadership in the Commonwealth and realized her mistake in making peace with Rick. Several years after Rick's death, Pamela is no longer an authority figure at the Commonwealth and keeps visiting her imprisoned son. In her elderly years, she seems to be confined to a wheelchair.
