Viewers were worried this storyline would be dragged out until Christmas, but you couldn't be more wrong!
As Theo's behaviour continues to intensify, it's not long before he is exposed as her stalker.
In scenes that are airing next week, Theo is left worried that Martin and Eve are on to him, so he takes the decision to confess to Stacey when they are alone.
But this is EastEnders so there's a little twist in the story. After his confession, Lily's waters break, and with the ambulance being held up elsewhere they are forced to deliver the baby themselves, all happening while Theo is still in the house.
Speaking about next week's episodes, Lacey Turner who plays Stacey told Digital Spy: "He's put on such an act in front of her for months and really supported her so he's the last person she would ever suspect," she added. "It's only when Stacey realises how deluded he is about their relationship that she starts to panic as she knows she's in danger."
"He's been tutoring Lily free of charge, and he's been so supportive with Stacey and the stalker situation. That's what makes it so hard for her because she has no idea who this person is that she's let into her and her children's lives for so many months." she said.
EastEnders airs these scenes next week on BBC One and BBC iPlayer.
