Viewers saw Eva arrive back in Weatherfield after leaving in February when she was wrongly accused of cheating on boyfriend Jason Grimshaw with his dad Tony - only it was Jason's brother Todd fabricating the whole thing.
The storyline paved the way for Catherine's maternity leave. She welcomed baby son Alfie, her first child, with fiancé Tom Pitfield in March.
But after resuming filming this summer, fans finally saw Catherine's return as fiesty Eva, and it certainly disappoint.
On Wednesday's episode (16 September), Catherine returned from France nursing a broken heart after her boyfriend, who she had met over there, cheated on her.
Back on home turf, Eva went to the Rovers Return to drown her sorrows, but she soon bumped into Todd and wasted no time in giving him a taste of his own medicine for sabotaging her previous relationship with Jason.
Guys thanks so much for your tweets re: Eva's subtle 'come back' so glad you enjoyed it. I've missed her too— Catherine Tyldesley (@Cath_Tyldesley) September 16, 2015
Grabbing the nearest thing to her, Eva picked up a pint of water and chucked it over Todd's face, giving him a well-deserved soaking.
Catherine tweeted after the episode: "Guys thanks so much for your tweets re: Eva's subtle 'comeback' so glad you enjoyed it. I've missed her too."
