It won’t look good! (Picture: ITV)

We recently discovered that Caleb Milligan (William Ash) and Tracy Robinson (Amy Wyatt) had shared a passionate kiss in Emmerdale. In fact, two passionate kisses.

When Tracy went round to Caleb’s to read the riot act about Caleb’s treatment of her newish husband Nate (Jurell Carter) at work, Caleb grabbed her and kissed her. After pulling away she thought for a moment and then rushed back for another kiss.

Since then they’ve been gazing lustfully at each other across a crowded Woolpack while Tracy insists is married and she’ll never stray, and Caleb says he is going to respect that.

But actions speak louder than words in soaps and their body language is clear. It’s an affair waiting to happen.

It has disaster written all over it (Picture: ITV)

In upcoming episodes the two once again have to meet up for work reasons, but Caleb takes the opportunity to tell Tracy how attracted he is to her – and they end up kissing passionately again.

Once again Tracy regrets this and tries to pretend that Caleb means nothing to her by persuading Nate to take the afternoon off so they can spend some time together.

But it’s Cain Dingle’s (Jeff Hordley) birthday so there are Dingle drinks at the Woolpack – meaning that Tracy is once again forced to endure the magnetic proximity of Caleb.

It’s all a bit too much to deal with and it’s not long before Caleb is following Tracy out to the corridor by the toilets (so romantic!) and they have trouble keeping their hands off each other and almost kiss.

This is obviously extremely risky behaviour in a pub full of Dingles and they’re almost caught by the birthday boy himself, Cain.

Imagine the ructions that would occur if Cain knew that his brother was carrying on a secret affair with his son’s wife. It would test Cain’s recently established brotherly bond with Caleb to its limits. In fact, the thought of Cain trying to wrestle with the moral ramifications is actually quite a juicy idea.

But for Tracy and Caleb almost being caught by Cain should be a wake-up call. Unfortunately Caleb can’t keep his eyes off Tracy as they head back to the bar and she reunites with Nate.

And when Caleb leaves the pub, Tracy follows him.

It’s going to end in tears one way or another.
