Supergirl.tv is reporting that Hell on Wheels actress Angela Zhou has joined the third season of The CW’s DC superhero show, and is set to play a character called Dr. Grace Parker.
The character is described as “a renowned surgeon in National City and has had quite a career in healing the sick and injured.”
There’s a lot of speculation online that Grace Parker could actually be Pestilence, the third Worldkiller – biological weapons created by Kryptonian scientists – alongside Samantha Arias/Reign (Odette Annable) and Julia Freeman/Purity (Krys Marshall).
Supergirl is currently on a break and returns to The CW on Monday, April 16th. Follow all of our coverage here.
