Carla plans the perfect surprise proposal in Corrie

But will Lisa's curiosity spoil it all?

9-15 AUGUST

When Carla and Lisa attend a life drawing class together, the evening is brought to a halt with another Betsy drama.

At the factory, Betsy reluctantly shows Carla the vest tops she’s been working on and how she inadvertently printed the wrong logo on them. How will Carla react?

At No.6, Ryan is thrilled after Carla confides in him that she’s going to propose to Lisa.

Later on in the week, Carla checks the post and confides in Ryan that she’s waiting for an engagement ring.

Whilst Lisa wonders what they’re whispering about she shows Carla a jewellery website, revealing her plan to have a ring made for Betsy’s 18th birthday, incorporating Becky’s fingerprints.

After excitedly taking delivery of the engagement ring, Carla calls at the Rovers and hands the engagement ring to Glenda, and asks her to slip it into Lisa’s glass of champagne when she arrives.

But when Carla calls Lisa at work and insists that they meet in the Rovers for a drink, will Lisa guess what is going on?
