Carl has a private chat with Colleen about the letters and he asks her to write the word ‘waste'. She is disgruntled by her ex-husband's accusations but writes the word regardless. Carl later cleverly asks Chloe to write a letter for Tom and as he dictates he includes the same word. Chloe incorrectly spells the word ‘waist' and Carl is horrified as the mistake matches an error on the letter. How will Carl react to the discovery that Chloe was responsible for destroying his relationship with Chas? Meanwhile, when Viv takes her new pet rabbit to the vets, Paddy is clearly nervous in her presence.
