Betty Gilpin has booked a return trip to Elementary in season 5, EW has learned exclusively.
Gilpin first appeared on the CBS drama in season 4 as Fiona Helbron, a brilliant and socially awkward software engineer, who met Sherlock (Jonny Lee Miller) and Joan (Lucy Liu) during a murder investigation. Fiona ultimately struck up a relationship with Sherlock.
“We certainly owe a status report for the Sherlock/Fiona relationship,” EP Rob Doherty recently told EW. “In the first few episodes there won’t be much mention of her, but we are working on a return for Betty Gilpin. Fiona is a thread that we won’t let dangle too long, especially considering how much we love Betty.”
Gilpin will be back for at least one episode, which is slated for mid-November.
Elementary returns Sunday, Oct. 2 at 10 p.. ET on CBS.
