At the McQueens, the family get to know Carter a little more over a light-hearted lunch date, as he reveals that he's trying to get John Paul a tutoring contract for underprivileged children.
The family are ecstatic by the news as the headteacher sneaks off to take a secretive phone call.
Elsewhere at Hollyoaks High, Lucas continues to lash out and Hunter is determined to help him through a new football team. And Carter praises the teacher for his creative way of keeping the troubled children at the school at bay.
