I see the introduction of Lisa as the reason to halt the decline in viewing figures and spice up the house, which to her credit she is doing very well. The makers have clearly realised that this series is becoming dull and unappealing by the day and a new house mate had to be chosen to enter the house. The timing of Lisa's appearance and the fact she hasn't been abroad (ala Josh style) makes me believe this is the case.
