I've never done anything like this before, but I suggest creating a template, such Template:Appearances, calling it in the infobox using and using the switch parser function in the template.

Then, you only need to update that template after each episode.

I'd also suggest using MassNullEdit from Special:WhatLinksHere/Template:Appearances after each time you update it to ensure all of the pages are updated accordingly.
