So I'm going in and doing some major updates with feedback from TooYube and GNick. Already got a new tab and tab end system worked out for episode pages. Same general layout, but mobile friendly and way more streamlined. Also trying to set stuff up in a way that you can just switch out the template names and you won't have to change much else.
With the new episode tabs, there's only one template for all the episode pages and subpages (it can detect which page type it's on), so there won't be any need for a different template on each subpage. I also dropped the box around the article since it's unecessary and is part of why it breaks on mobile. Now it
The "tab ender" has also been updated, though there's three different versions for that (there's a lot more variables there that make trying to do just one difficult). One for the main episode page, one for all episode subpages, and one specifically for the image galleries on specials and movies (those are often split onto 2+ pages). Still way more streamlined than it was before.
Update: Actually, nevermind on the 3 different versions. I was able to figure the coding out and now the {{EpTabEnd}} will link you right on all the subpages in addition to the main. Also have it so it will automatically fill in the episode name for you. You still will need to manually enter the "previous episodes" and "next episode" names though, though I think I figured out way to automate that too.
Also working on the new episode infoboxes and CSS for that. Got all the parameters from the old episode infoboxes moved over and working on carrying over some of the color theming as well.
Also, all the new templates display on mobile correctly.
Some episodes I was testing this stuff on below. Some stuff still a WIP.

Also fixed up the theme a bit. Got rid of the seam in the background image and dark mode's got a background now.
