Yeah the actress was in the paper there last week and she's finished with the show. In it for 10 years apparently so felt it was time for a change.
A pity for male fans of Ros na Run as she was the hottest girl in it for years. Even though she had to wear a dodgy looking synthetic scar for the past 6 months.
Seems to me they're playing safe atm - they have so many times where they could build up drama or controversy and then it just fizzles out (Roise and Ciaran, Katy and Ciaran, the whole Grace/Alice thing, Evan and Niamh and the botched abortion...).
