Casting and Development
Sinead Keenan got told by her agent told her she would be auditioning for a show about a werewolf, a ghost and a vampire. She then auditioned for the show and got the role of Nina. The first plan for Sinead Keenan's character Nina was to be written out of the series at the end of season one. When creator Toby Whithouse saw Keenan's and Tovey's great dynamic on set while filming he decided that the character Nina should stay. Since the producers enjoyed the relationship between Nina and George very much they decided that Keenan should become a series regular within the third season. Nina remained in the series for another year until Keenan decided to leave the series.
Leaving the series
In January 2012 Sinead Keenan announced on Twitter that she would not return to Being Human. She said that she had a heavy heart but also felt a little relief. For her it was a difficult decision, after having three wonderful years and one of her best in her acting career. She also said that her departure would happen off-screen since she hasn't filmed anything for series four.
Characterisation

Reception
Mark Oakley from Den of Geek thought that Keenan had a „rather thankless role in Doctor Who“, however he thinks that Keenan is much better in Being Human, „lending a bit of weight to the character of Nina, who is going to have a larger role to play“ in series two. According to The Daily Telegraph Nina’s relationship with George was perceived very well by fans and critics. Matt Risley from IGN thinks that Sinead Keenan and Russell Tovey "bring an intimacy and humanity" to Nina's and George's relationship that "effortlessly straddles the line between horror, comedy and drama". Matt Wales from IGN praises Sinead Keenan's "mesmerizingly broken performance as Nina" when the werewolf-in-waiting tries to deal with her new nature.
