‘Grey’s Anatomy’: Kate Burton Returning As Meredith’s Mother In Season 18

etcanada.com:

A blast from Meredith Grey’s past is back. Kate Burton will return for multiple episodes in the upcoming 18th season of “Grey’s Anatomy”, ET confirms.

Burton will reprise her role as Meredith’s late mother, Dr. Ellis Grey, though it is unclear in what context she will be appearing.

Ellis, who was a brilliant surgeon during her heyday, had been suffering from Alzheimer’s when she died of a heart attack in season 3.

The “Grey’s” vet will first appear in the season 18 premiere, as Deadline first reported, and recur throughout the season. Since her character’s death in 2007, Burton has appeared in a handful of episodes, mostly in dream sequences or alternate reality episodes.
