Home and Away's Leah Patterson-Baker will be left humiliated when her secret romance with colleague Zac MacGuire is publicly exposed.

Leah (Ada Nicodemou) has been trying to keep her romance with Zac (Charlie Clausen) under wraps out of respect for her teenage son VJ, who is a student at the school.

When Matt Page (Alec Snow) captures them kissing as he films an end of year video, the secret looks in danger of being revealed.

After showing Sasha the footage of the teachers kissing, she sensibly tells him to delete it. However, as students and teachers gather to watch the video, it is clear that Matt hasn't taken Sasha's advice.

Clausen told TV Week: "Leah and Zac have only just got together. Out of respect for VJ, they are really trying to keep thie relationship quiet. Leah wants to speak to VJ first and ease him into it, but she hasn't had the opportunity to do it.

"Matt's version of the video has the hidden footage of Zac and Leah. When it is shown, all hell breaks loose. VJ is humiliated in front of the whole school and storms out."
