Flustered by the events from the night before, Gemma (Sarah Alexander) is frantically baking cakes for the twins' school function. Surely she can convince Billy (Robert Sheehan) that there's nothing romantic between them?! That is assuming she can convince herself. Not a natural Nigella, Gemma's efforts end in a huge mess and she is forced to strip off to her bra, only to give Billy an eyeful. Gemma, Alfie (Jonathan Bailey) and Billy arrive at the school and - totally unaware of the chemistry between his best friend and his mum -Alfie sets Billy a challenge to see who can kiss a 'hot mum' first. Elsewhere, Inca causes upset by taking over during a meeting with the twins' teachers.
