Eileen Callan (also Day) is a fictional character from the British soap opera Family Affairs, played by Rosie Rowell from 2002 until the end of the series in 2005.
On the day of Pete's trial, Mike turned up and attempted to rape Eileen, Dave and Lucy where quick to intervene.
Pete, having been acquitted of Roy's murder came home to witness this and devised a plan to dump Mike's body at a footbridge.
Eileen then found herself at the mercy of a stalker who had known of her plot; It turned out it was none other than her old friend Trish Wallace, who had also dated Mike when they were younger.
This culminated in Pete throwing Eileen in the River Thames on their first wedding anniversary, after playing the tape back to her.
In September 2005, on the day of Thomas' christening, Trish appeared upstairs at the pub with a gun and held the Callans and Katie hostage.
After Thomas had been taken into care following Trish's arrest, Eileen's mental state went from bad to worse, alienating many locals including her friend, Chrissy Costello.
Two months later on New Year's Eve (The series' final episode), Eileen returned to Charnham having won the lottery and purchased two houses in Chigwell, one for her and one for her friend Chrissy and her family.
