Freda Foh Shen was booked to portray the role of Watson's mother in Elementary -- TV Line reports.
Mary Watson appears in Episode 9, slated to air Dec. 13, and she’s not very happy about her daughter’s choice of profession.
“Mom will meet Sherlock,” confirms the EP. “Given what we know about mom — or heard about mom — and given what we know for sure about Sherlock, you can see it going a certain way. I feel like we’re going to tell a story with a few lovely, little surprises.”
'Elementary' airs every Thursday on CBS.
