In the Elementary episode ‘Fidelity’, an old case that Sherlock (Jonny Lee Miller) and his former protégé Kitty Winter worked on in London has come back to haunt him. A series of murders stemming from the old case is now connected to a government conspiracy. And on a personal note, Kitty shares some “life-changing news” with Sherlock which strains their relationship.
Former protégé Kitty Winter is portrayed by Ophelia Lovibond. Americans will recognize the English actress from her roles in the films Man Up (Jessica), Guardians of the Galaxy (Carina), Mr. Popper’s Penguins (Pippi), and No Strings Attached (Vanessa), among others. Elementary airs Sundays at 10pm on CBS.
