Hilda the cat won’t leave Tony alone as he tries to have breakfast. He blames Pat for giving the animal treats – she calls it positive reinforcement but Tony is angry, telling her it’s not working. He picks Hilda up and puts her in the hallway. Later, while catching up, they realise haven’t seen her since breakfast time. Pat is concerned that Hilda might be missing. What if she has run away or been hurt? Peggy would be devastated! Susan asks Chris whether Alice is seeing Harry that evening as he has Martha. She has her doubts about him, pointing out he says all the right things but seems too smooth. She complains that Adam is being a stick in the mud at work and stopping her and Clarrie from having a chat and a laugh. She has a plan to take him down a peg or two. Susan puts her plan to prank Adam into action, telling him they need ingredients for a special Valentine’s Day ice cream. As Adam goes off to make a list, Pat reports that Hilda is missing and asks if they’ve seen her. They search in vain, during which Adam asks about the ‘aphrodisiac’ ice cream, confirming his suspicions. He starts planning his revenge. Meanwhile, Tony has had enough of the search and returns to the farmhouse only to find Hilda warm and cosy, curled up in his chair. Pat says Hilda is just a cat but Tony is adamant she is a demon in feline form.
