In next week's episodes of the BBC soap, Carol starts staying with Glenda (Glynis Barber) after deciding that her current home holds too many unhappy memories following her son Billie's death.
Carol's decision to seek support from Glenda comes after her brother Max (Jake Wood) insists that she cannot move back in with him.
Speaking to Inside Soap, Coulson commented: "Carol has to leave Bianca's house - she doesn't want the reminders. She doesn't really know Glenda, so perhaps she can reinvent herself.
"It's a strange pairing, but it'll be interesting to see if they can find common ground."
Reflecting on Carol's ongoing grief storyline, she said: "I'd like to show viewers that Carol is strong enough to transcend all of this, because people have to - but it won't just go away."
