Hey, Tammzz, NikkiSarah, I've been thinking about having Character and Episode Bars on Character and Episode pages, it would be a type of navigation for getting from one episode to the next or from one epsisode to any other episode, this is how they would look:

This is how I currently have designed my one on Mom Wiki we could also do it with Characters. Feel free to comment below and consider it. Feel free to have a look at how it works on here
