The fiery mum reacts in fury when she hears that Billy has made a move on Carol by kissing her during a night out at R&R.
Storming round to the club after a confused Carol has returned home, Bianca rages at Billy - asking how he could have tried it on with Carol knowing the state she's currently in.
When Billy goes on the defensive and becomes rude and belligerent towards Bianca, will she be able to resist the urge to let her fists do the talking?
