Gemma raises the jealousy of the other mums at the school gates when handsome Tom asks her on a date. She's beyond nervous - but it's the surprise return of son Alfie from international travelling with new friend Billy that really throws her.
After forcing Jason to give Alfie a job on the sandwich run, Gemma finds herself at a self-defence class run by Tom. When an inflamed Jason gate-crashes the class he is attacked from all sides, and Billy must decide if he can carry on living under Gemma's roof.
It's Alfie's birthday at the bar and Gemma finds herself encouraging Billy to date another woman. Tom helps Fran pull the man of her dreams and Inca overhears some information that has a disastrous effect on her relationship with Jason.
Tom hosts a dinner for Gemma who shows up with an uninvited guest. Much to the annoyance of a lovelorn Jason, Inca goes on a blind date at the bar where she inadvertently gives Billy some advice about love that forces him to finally confront Gemma.
