Case 1 - inconsistent index page format is inconsistent (see below) so I don't think it is sensible to get from this

Case 2  The detail page has the Series, Episode and Episode Number of Number of Episodes but I am struggling how to get

The Series and Episode number are on the Page in the following elements
<h2 class="episode-information__heading episiode-information__heading--title" itemprop="name">
                                                    Series 17
                                                 -                                                     Episode 44
                                                                        <b class="episode-information__heading--subtitle">Yorkshire Dales</b>
                                          </h2>

But sometimes the <b class ... subtitle name </b> is not present
