Call the Midwife fans are about to see the return of a character who sounds pretty stoked to come back.

Chatter On 'Call The Midwife' Christmas Special

On Saturday, the series' Facebook page announced that Sister Monica Joan, played by Judy Parfitt, is going to return to the British drama. The post also showed what the actress had to say about her character, a part that is not easy to possess.

"I do enjoy playing Sister Monica Joan because she's multi-coloured and unpredictable. It's not an easy ride because she's complex and that's why I love her," Parfitt said. "She sometimes loses the plot and other times she's incredibly sensible, helpful and guiding. She constantly shifts and changes and that needs to be thought about a great deal because she goes from one extreme to the other."

The actress then pointed out how her Sister Monica Joan is different from the other characters, one of them being a certain craving she has.

"She's tricky, but I love that I can really do anything with her, and that she loves cake!" Parfitt said. She's totally obsessed with cake; it's like a drug for her."

Parfitt then dished on the success that the series has gained, something that doesn't happen very often.

"To get a show that is so hugely successful and adored is rare," she said. "The success of the show is down to the scripts, but the casting has also been fantastic. The period detail is wonderful as well."

Call the Midwife Season 4 will air in the United States on March 29 on PBS.
