Sadie King (Patsy Kensit) is executing a calculated plan to destroy Caleb Miligan (William Ash) and his wife Ruby (Beth Cordingly) in Emmerdale, working from inside their home without Caleb realising what she has done.
Sadie is on Joe Tate's (Ned Porteous) payroll, hired to obliterate Caleb and Ruby from the inside out. Joe recruited her just as she prepared to leave the village after being exposed for lying about dead Jimmy King (Nick Miles) cheating on his wife with her. With no home or money, Sadie had nothing to lose and everything to gain, having already started laying the groundwork by becoming Ruby's friend.
Sadie sows seeds of doubt
Caleb is proving a challenge, but Sadie begins by sowing seeds of doubt. The first seed is the suggestion that wine-seller Ruby might have a drinking problem, as Ruby constantly has a bottle of wine in her hand. Through gentle manipulation, Caleb's concerns for Ruby's drinking grow. Sadie tells him she will look after Ruby, and Caleb willingly trusts her, distracted by concern for his wife and failing to see Sadie slowly moving in for the kill.
The next stage of her manipulation is to convince Ruby that Caleb is trying to control her. Sadie takes Ruby to the pub and tells her Caleb asked her to keep an eye on Ruby, which brings out Ruby's rebellious side. Sadie then stirs the pot with discussions about Manpreet's (Rebecca Sarker) past, leading to a debate that makes Ruby look bad. As Caleb steps in, Sadie turns on the friendly charm to Ruby while lying to Caleb that she is helping his wife.
The plan comes together
Sadie's plan is working, and the cracks are showing. She now outright suggests Caleb is controlling, and though Ruby is not initially convinced, she sees that Sadie is just trying to help. Sadie has Ruby right where she wants her and easily convinces her to drink wine before an important business meeting. Caleb walks in on this, having had Sadie in his ear that Ruby has become a booze hound.
He hits the roof, which plays into Sadie's game that Caleb is trying to control Ruby. The client witnesses this, and the Miligans all but lose the deal. The couple blame each other, and Ruby storms off, leaving Caleb to believe her problem with alcohol is real. Joe's revenge plan is coming together nicely.
