I'm aware this is a fairly large PR, so please know that I'm available for discussing, editing, or justifying any of the changes made.

Thank you for any assistance you can provide.

Best, Vini

Hello @alee, thank you for the reply.

I understand. I will keep that in mind for future contributions. Would you like me to break this up into separate PRs, one for each episode? Or may I leave it as is?

Best wishes, Vini

Let's leave it as is as there is a considerable amount of work in here already, just wanted to point that out for future reference :+1:

I'll do my best to review this and get it merged in the next few days - thanks!
