Pimply Paul (seasons 4 and 5)

Paul Peregrine, better known as Pimply Paul is the husband of Polly and the father of Vera. He is also Henry and Peter's first cousin-in-law.

Why We Should Be Quite Impressed About Him Now

 * 1) From Series 1-3,  Paul was often a grouchy and grumpy teenager often showing contempt for Henry despite adoring his wife and daughter and liking Peter. However the forty-seventh episode of series 3 titled 'Horrid Henry delivers the Milk' shows a huge change of character growth towards how he treats Henry.
 * 2) While some other websites state the change of how Paul treats his younger cousin-in-law to eventually seeing Henry as some sort of a surrogate son, this is highly overexaggerated considering Paul only has featured in 4 episodes so far ever since the events of the Horrid Henry delivers the Milk' episode. He has featured in three episodes in series 4 and only one episode in series 5.
 * 3) Pimply Paul is shown to be more funny, kind and appealing from series 4 onwards compared to his snarky rude attitude shown in series 1-3.
