This post accurately predicts the ending of Samurai Jack.
Proceed with caution.
Jack stays in the future; sends Aku to the end of time.
Here’s what we know about the ending from Genndy:
>it’s the ending “we never knew we wanted”
>it will make us tear up/is bittersweet
>it might be more about Aku’s end than Jack’s
Here’s what we know about Jack in season 5:
>he’s haunted by his failure to be the heroic protector he vowed and trained to be; feels guilty
>he’s obsessed with the past
>he’s spent 50 years, two-thirds of his life, in the future, without aging
>Jack and Ashi are going to form a close bond
Jack needs to move on from his guilt, so that he can be happy and healthy, like he deserves. He’s obsessed with the past, but he clearly no longer belongs there. He additionally may decide he'd rather be with Ashi.
Here’s what we know about Aku in season 5:
>as Jack is haunted by his past, Aku is haunted by his future; he can never rest/his reign could be nearing its end because Jack could ambush him, or find a way back to the past and defeat him there at any moment, as far as he knows; Jack can’t die from old age and it’s extremely difficult to kill him, making him effectively nearly immortal, and Aku’s anxiety eternal
>he may have, or may form, a close bond with Ashi, as well
Aku, as the villain, ought to get his just desserts, and what better way to do that than use his fear of the future against him, and make his weapon against Jack, in the form of Ashi, a source of strength for Jack instead.
