I decided it was time for me to rewatch Buffy and Angel and I wanted to do so in the right order. I found this blog post that gives a recommended order and what episodes are especially important to sync up because they reference the other series.
But the episodes are just listed with consecutive number. That in combination with Disney+ insisting to show me the German titles for the episodes made it necessary to keep counting to know when to jump over etc.
So I made myself another version of the list that shows the common season/episode codes for the episodes.
