Earlier this month, show chiefs announced the casting of The Kumars actor Vincent Ebrahim as the corrupt character, who recently spent time in prison with resident gangster Trevor Royle.
As Big Bob helped Trevor (Greg Wood) out during his time behind bars, he now wants a favour in return and will stop at nothing to get it.

After Trevor encourages Grace to speak to the doctor about their chances of conceiving, she surprises him by revealing that she has made an IVF appointment.

Hollyoaks airs these scenes on Friday, August 8 at 6.30pm on Channel 4.
