As the popular drama series Teulu returns to S4C, one new character is bound to make an impression.
On Sunday 8 January, we'll follow the eventful lives of the Morgan family, all the tensions at the Glan Don surgery, the Cei bar and restaurant, the romance, the arguments and disagreements which are so much a part of Teulu, the series created and written by Meic Povey and Branwen Cennard and filmed partly on location in Aberaeron.
But at the heart of everything, it will be hard to ignore Haf Owen, the determined Marketing Director who has come to Llŷr Morgan's club to try to keep the staff and owner in order.
Haf is played by actress Lisa Marged, who is originally from Nantycaws near Carmarthen, and she loves playing her character.
"Haf is intelligent, remarkably active and very passionate about her job. But she's had to adopt a thick skin very quickly and as time goes on people think twice about crossing her," says Lisa, 24, who now lives in Cardiff.
"She's used to co-operating with professional people who are serious about their work, so moving to manage this particular club has been an eye-opener for her. Some people try to take advantage and challenge her, but believe you me, Haf Owen is not one to avoid conflict and give up," adds Lisa.
Lisa is familiar to many S4C viewers since she has acted in series such as Pen Talar, Alys and Zanzibar, but this is her first big acting role on television.
"I admire Haf's passion for her work and I feel the same passion for my work as an actress, but I don't have a thick skin like her. I would have crumbled by now if people treated me the same way they treat her," says Lisa, who is a talented mezzo soprano singer and reached the final round of the Bryn Terfel Scholarship in 2009.
"I've always been a big fan of Teulu and I remember telling Mam that I would love to be a part of the series and who'd have thought that years later I'd be a member of the cast. I've had the warmest of welcomes. Actress Mair Rowlands whispered in my ear on my very first day, 'No need to worry, despite how cheesy it sounds, we're all one big family,' and that's very true."
