Netizens are boiling over as the latest episodes of Coronation Street suggest a shocking theory: Ollie – Dee Dee Bailey’s new lover – could be DI Costello’s lost son.

It’s worth noting that this detail not only changes the entire relationship between the characters, but can also lead to a series of dark secrets related to Becky’s death.

From the very first time he appeared, Ollie made the audience wonder.

Instead of just focusing on the sweet love story with Dee Dee, this character often hangs around the police station, closely observing Lisa and Carla, and asking meaningful questions.

On the Reddit forum, an audience member wrote: “If you pay attention, Ollie and Costello appear at almost the same time, are around the police all the time, and both act strangely. I wouldn’t be surprised if Ollie is Costello’s son.”

This theory quickly spread. If true, Ollie was not just a “romantical guy” who came to romanticize Dee Dee’s life, but a strategic pawn in Costello’s plan. The purpose? Maybe to approach Lisa, Carla or to get information about the Radcliffe case. This also explains why Ollie seemed so “convenient” to enter Dee Dee’s life – it was all a premeditated plan.

The interesting thing here is: the audience has not known anything about Ollie’s past. He appeared unexpectedly, creating a likable impression, but lacked a clear background. Meanwhile, Costello was already suspected of being a “dirty cop”, hiding shady details about Becky’s death. The fact that the two have a blood relationship is a completely reasonable twist, both explaining the coincidence in the time of appearance and opening up many dramatic conflicts.

If this theory turns out to be true, Lisa’s character will once again be thrown into turmoil. Not only will she lose the trust of her colleagues, she will also have to face the possibility that the person flirting with her group of friends is actually Costello’s “spy”. In a show known for its shocking twists and turns like Coronation Street, this would certainly be a terrifying, but also extremely engaging, twist.
