Dynamic help

I’m trying to create an embedded video site.
How it’s setup.
I have a category with the name of the show.
Then each episodes as a post under the category.
In each episode there is a div with a list of the episodes links up to a selected point. Example

Episode 1 (current page)
Episode 2 (next post +1)
Episode 3 (next post +2)
Episode 4 (next post +3)
Episode 5 (next post +4)

Season 2 (next post +5)

I’m thinking a loop logic with database info.

So when I create a new episode post, the whole loop logic wont need to be changed(dynamic), except for the point of where it stops for the next season.
