Yep, that was Buffy's mom on "The Following."
Kristine Sutherland, a.k.a. Joyce Summers to legions of "Buffy the Vampire Slayer" fans, appeared in the Monday, Feb. 25 episode of the Fox drama as Agent Parker's (Annie Parisse) mother in flashbacks to the time the agent confronted her parents 15 years after fleeing a cult.
Post-"Buffy," Sutherland's other TV credits include "Comanche Moon" and "One Life to Live." "Buffy" creator Joss Whedon recently revealed that killing off Sutherland's character was one of the toughest deaths he's ever written. Hey, at least she's alive (in a flashback) on "The Following."
"The Following" airs Mondays at 9 p.m. EST on Fox.
