An item can carry several credits blocks with mid- and post-credit scenes between them, and Plex flags the one that really ends it. The player left at the first block. Now the Plex-final block moves on (by the auto-skip or the Skip button), an earlier block is only skipped to its end by the button, and with no final flag the last block ends the item by the button alone.

// What skipping an intro/credits marker does. An item can carry several credits blocks — mid- and
|
|
// post-credit scenes play between them — so only the block that ends the item moves on to the next
|
|
// one: the block Plex flags `final`, else the last one. Every other credits block is skipped like an
|
|
// intro, to its own end. And only an end Plex itself vouches for is left on its own (the credits
|
|
// auto-skip); an end inferred from the list waits for the viewer's Skip — the stretch after it may
|
|
// still be the show.
