Katherine Kelly plays Hannah
Hannah is HIM's mother. Having got divorced two years ago following her husband's affair, she's now set up home with new partner Victor and his daughter, who is about the same age as Hannah's son. Plus, she and Victor have a new baby. She doesn't have as much time for her son as she used to, but she loves him dearly and doesn't believe he could ever do anything really bad...
"She's a bit of a jaded character in many ways," says Kelly of Hannah. "She's definitely not had the life she thought she was going to have. Like many women, she sacrificed a lot for the family unit. I hope people can relate to [her] as she's just a mum doing her best."
Kelly is well known for her appearances in Happy Valley, The Night Manager and Mr Selfridge, having made her name playing Becky for six years on Coronation Street. She'll star next in BBC3's Doctor Who spin-off Class.
