Relationships are always tested in Serial Dramas and in tonight's Emmerdale it was no different.
Ever since Dr. Liam Cavanagh (Jonny McPherson) quickly started a relationship with Leyla Harding (Rokhsaneh Ghawam-Shahidi) after Bernice Blackstock (Samantha Giles) departed the ITV/STV programme, it hasn't sat well with Liam's daughter, Leanna Cavanagh (Mimi Slinger).
Earlier in the episode, viewers saw a mystery person break-in to Take A Vow and sabotage Leyla's whole arrangement for potential clients Mindy & Saxon. No stone was left unturned. You name it, it was destroyed and when the engaged couple saw the devastation, they cancelled Leyla's plans and went elsewhere.
All viewers know is the person was white who ransacked Take A Vow.
Later, believing it was Leanna who trashed the business, Leyla confronted the troubled teen outside Bob's Cafe. A war of words was soon underway but it became too much for Leyla as she slapped Leanna across her face in the closing moments of this evening's episode.
Fans of Emmerdale took to Twitter giving their reactions.
Even the team at Woolie Weekly were shocked at what occurred before their eyes.
Will Leyla live to regret hitting Leanna?
Tune in on Monday at 19:00 on ITV/STV.
