Hardy finds Tom's computer, which reveals that he fell out with Danny after the latter found a new friend. At the same time, following an email Hardy traces Danny's phone to the person Ellie's sister Lucy saw dispose of a bundle on the night of the killing. This is the new friend, who makes a confession tying in with what Susan thought she saw and with Steve's psychic vision, a person whose repressed love for Danny led to a terrible conclusion after Danny threatened to expose the relationship. Shock, rather than relief, takes hold of Broadchurch as a result before the town comes together to light beacons in Danny's memory.
