Emmerdale spoilers: Big twist as Nate Robinson catches Caleb Milligan getting passionate – but it’s not with Tracy Metcalfe

In Thursday’s (January 25) Emmerdale episode, Nate Robinson (Jurell Carter) received a shocking revelation when he saw Caleb Milligan (William Ash) in a passionate embrace—but not with Tracy Metcalfe (Amy Walsh).

Nate had confided in Belle (Eden Taylor-Draper) about his worries, wondering why Tracy was behaving oddly.

Then he did something about it, going through her phone and finding erased texts from Caleb. Nate wasn’t persuaded, despite Belle’s best efforts to calm him down by suggesting Tracy may have done this to free up space on her phone.

Tonight, Nate came to the conclusion that catching Caleb—and maybe Tracy—in the act was the only way to find out the truth or have his doubts dispelled.

Tracy told Nate she was leaving for a business trip and would not be returning until the evening, then she packed her luggage and slipped over to Mill Cottage.

Tracy admitted to being afraid of what would happen to Nate and young Frankie if she started to fall in love with Caleb while they were sitting on the couch together.

Nate was prepared to confront his uncle and wife about their alleged treachery as night fell and Tracy contemplated remaining with Caleb rather than boarding her train.

Knowing of Caleb and Tracy’s extramarital affair, Nate was trailed by Moira (Natalie J Robb) and Nicky (Lewis Cope) as he made his way to the residence.

Nate saw Caleb on the couch as he stormed into the living room.

He cried out to get free from the lady he was seeing, but when he saw it was Ruby and not Tracy, he was taken aback.

Ruby, portrayed by Beth Cordingly, is Nicky’s mother and Caleb’s wife. She will “put a real spanner in the Dingles,” according to others who characterise her as “an absolute firecracker.”

However, what does Ruby’s presence in the Dales signify for Tracy and Caleb?
