CBS' ELEMENTARY
- Betty Gilpin (Nurse Jackie) will appear in at least two episodes of the drama's fourth season. She will play Fiona Helbron, a brilliant and socially awkward software engineer, who meets Sherlock (Jonny Lee Miller) and Joan (Lucy Liu) during a murder investigation. She describes herself as "neuro-atypical" but others say she's just a high-functioning autistic. She has a hard time reading people, rigidly adheres to rules and can't lie. She then finds herself drawn to Sherlock.
