The Following unleashed a game-changer in last night's episode in the US.
In 'Evermore', the tenth episode of the season, Joe Carroll (James Purefoy) is executed by lethal injection.
What to Read Next
The serial killer accepts his punishment after a series of final confrontations with his nemesis Ryan Hardy (Kevin Bacon), in which Joe becomes convinced that his legacy will live on through Ryan.
"Quoth the raven - nevermore," Joe says to Ryan before dying.
But it's not the last time we see Joe, as Ryan hallucinates him while drinking in a bar.
"When Ryan let Joe back into his life, it was almost like letting a virus or infection back in," executive producer Brett Mahoney told TVGuide.com.
"It's really about the place that Joe occupies in Ryan's mind, and Ryan has got to find a way to exorcise that out. That'll be his process in the last five episodes of the season.
"We definitely end with a new trajectory that would take us forward into the next season in a very interesting way."
The Following continues on Fox in the US and on Sky Atlantic in the UK.
