After sleeping with Melissa, Alan finds it hard to let go. He carries on seeing her at Charlie's house and acting as if he still lives there. Eventually, he takes advice from Charlie and Evelyn and ends it with Melissa by text message - causing her to take her anger out on Charlie. Upon his return to Lyndsey's, Alan accidentally sets fire to her curtains, causing a mass fire and leaving them homeless. Title quotation from: Alan, lying to Lyndsey and describing how Charlie is prickly on the outside but a sweetheart on the inside.
