In the process of trying to help with cleaning it up, Barry suffers a back injury, leading Yvonne to call on a former boyfriend, Julian Dalrymple-Sykes, to help her out in his absence. Meanwhile, the graffiti vandalism proves problematic to such a point, that Ted decides to step in with an ingenious plan to put a stop to it.
