This week, Carla Connor is the typical female protagonist with no room for rest.

She goes to the hospital to see Costello, her goal clear: to extract more information to expose Becky, to definitively conclude that Becky was behind the attack and the previous dirty tricks.

But Costello doesn’t give Carla a straightforward answer.

Instead, he mutters words that sound both nonsensical and seem to be trying to slip a clue into Carla’s hand while she’s half-conscious.

And that very moment shifts the story in a different direction.

What makes this storyline compelling is that Carla isn’t the type to just listen and then ignore it. Carla is the kind of person who, when she smells a secret, will pursue it to the end. So, Costello’s confirmation of Becky’s involvement, followed by a series of strange words, is like opening another door: this case might no longer be confined to Weatherfield.

And so the Corriedale theory emerged. The strange words Costello uttered sounded like a kind of coordinate, a hint of a location, enough to lead Carla away from the town and into a more dangerous pursuit. Corrie is very good at planting a small line that triggers a larger storyline, allowing viewers to piece together the fragments and feel like they are participating in the investigation alongside the character.
