When Patsy blames The Bear for Richard walking out on her The Bear runs away, but doesn't get very far as he is captured by evil circus ringmaster (Russell Brand).

Helena, distraught, turns to neighbour Keith Lemon for help. Armed with his new, finely tuned Ninja Skills which he has been learning throughout the series, he sets out to rescue The Bear all in a bid to win Helena's heart.

Keith saves the day but the happy ending is turned on its head when Richard returns and the wedding is back on...
