On screen, Rush's character Anna and her screen husband Eddie (Steve Huison) recently saw their son Gary (Mikey North) sign up for basic training, before going AWOL for a short period.
Speaking to Digital Spy on the red carpet at this year's British Soap Awards, Rush said: "The army [story]'s going to play out a little bit longer yet... and we're really going to stick to the truth and hopefully it will portray a lot of what's going on in the country at the moment."
Meanwhile, of the Windass adoption storyline, she added: "Fundamentally Anna is a real mum and now Gary's gone, she's found a little bit of room in her nest... she was so good with Chesney... I don't know if they get to [adopt] or not, we have to wait and see."
