However, when Tina tries to back out of the arrangement, she is threatened by Izzy's overbearing father Owen (Ian Puleston-Davies), who says that he will hurt Tina's boyfriend Tommy Duckworth (Chris Fountain) if she changes her mind.
Tina was seen arguing about the surrogacy plans with her reluctant partner in Monday night's double bill (September 17).

A delighted Tommy then approaches Rita Tanner (Barbara Knox) for the money to pay Owen back - unaware that the builder's threats have caused Tina to change her mind again and go ahead with the surrogacy.
"Tina goes to the clinic behind his back," a show insider said. "He's distraught, but of course he doesn't know she's only doing it to protect him."
Coronation Street airs on ITV1.
