The final moments of the Season 4 finale of The Handmaid’s Tale show a headless body hanging on a wall in the middle of the forest with the words “nolite te bastardes carborundorum,” which translates to “don’t let the bastards grind you down,” scrawled on it behind him.
It is, presumably, Fred. There’s also a scene of a finger with a wedding band being delivered to Serena at her cell. It, too, likely belongs to Fred.
In that regard, he is most likely very much dead with no hope of coming back in the future. This means The Handmaid’s Tale is officially rid of one of its top villains. What happens in the wake of his death, however, and what it means for both Canada and Gilead moving forward is anyone’s guess. What’s more important is what June plans to do now.
