Llewellyn has been known to get a little out of his own depth, such as when he challenged Boycie to a pub quiz in More Questions Than Answers and lost ten thousand pounds that he didn’t have in the first place. He has also accused Boycie of things that he hasn’t done, such as in From Here To Paternity when Boycie's dog, Earl, supposedly made Llewellyn's ‘slapper of a dog’ pregnant, which Earl didn’t. Llewellyn tends to speak first, think later, and generally lands himself in a lot of trouble. In the episode "The Departed", Llewellyn is a special constable.
