Before Billy was revealed to be 'Mr. X', and Hayley's ex boyfriend, he was given a number of challenges by Big Brother. These included:
Day 2: Saying "Goodnight Hayley, sweet dreams" before going to bed;
Day 3: Becoming Hayley's best friend and waiting on her 'hand and foot' for an entire day;
Day 4: When asked to take a housemate with him to feed the animals, he had to choose Hayley; and
Day 5: Becoming Andrew's best friend for an entire day.
