S1, E2: Adam and Sarah's relationship is blossoming. When things are at their best, Sarah takes the opportunity to tell Adam how important it is that he and Wilfred get on well. She gives Adam the 'single mum' speech-she and Wilfred come as a package. Adam convinces her that he loves Wilfred and to prove it he decides to spend some quality time with him. Wilfred is in his den - depressed. He's sleeping more than usual and he's gone off his food. He says he's very sick and "could be on the way out" - this may have something to do with the pizza Adam bought him the night before. He gives Adam a list of instructions of what to do should he die. Because Adam has done the "naughty boy" on Sarah - he is therefore obliged to look after her. Adam and Wilfred have a bonding session in the den - swilling beers and pulling bongs. Wilfred bemoans his lost tennis balls. A cheerful Adam offers to climb on the roof and retrieve them. In doing so, he falls and has to be taken to hospital. He wakes to find Sarah by his side. She tells him that Wilfred has been worried sick and has been fretting. When Adam arrives back home in a neck brace - Wilfred greets him with genuine glee. But this is short lived.
