Gerard is revealed to be alive. He is still suffering from the effect of the rejected Bite. His cancer is now vanished, but his body is continuously producing and ejecting black ooze. He is institutionalized at a medical facility and confined to a wheelchair.
Motel California
Gerard is visited by Chris for information. Chris brings up his uncle Alexander Argent, Gerard's brother. Alexander had committed suicide to follow the hunter's Code. He asks Gerard for the name of the Alpha who Bit him. Gerard smirks, answering "Deucalion".
Currents
Days later, Chris comes to him again for intel on the Alphas' leader, but this time Gerard is not so willing. Chris leaves but he tells his despicable father, he is going to tell him their family's story of Deucalion, and he is going to tell him the truth. Shortly after Chris' departure, Gerard's next visitor is Allison who'd followed Chris.
Visionary
Allison brings Scott to Gerard for information on Deucalion. Scott has to siphon pain from Gerard as his end of the deal. Gerard ascertains the Darach could be committing human sacrifices to destroy the Alpha Pack, saying the lengths one would go to defeat someone like Deucalion would certainly surprise someone.
He's paints himself as the victim in the story, when he's really the villain.
Gerard tells them the story of what happened ten years or so earlier. He recalls when Dr. Deaton came to announce a meeting between Deucalion and his Pack. The Alpha was offering a peace proposal meeting in an abandoned distillery. Gerard references William Blake: any sinister person intending to be your enemy always starts off with being your friend, and the fable of the Scorpion and the Turtle. Gerard recalls he knows a werewol's nature. He recounts the peace offering was an ambush, lies that Deucalion's Pack members killed the hunters that accompanied Gerard. Gerard eventually blinded Deucalion by gouging out his eyes. However, Gerard later says while Deucalion lost his eyes, he's not always blind. He's able to see as a Wolf.
Gerard plays amicable saying he thinks about Scott, how he'd got the Bite to cure his cancer, wondering "when it became my nature to believe most things couldn't be asked for but had to be taken. Scott talks back at the old man saying he doesn't believe him. He listened to his heartbeat all the while he was telling his "story" and it was steady. Gerard claims he was telling the truth. Scott counters it could be because Gerard's just that good a liar. The werewolf grips Gerard's arm painfully and gets in his face. He threatens the heartless man if he lied, and innocents get hurt because of it, Scott tells Gerard he'll be back "to take away more than (his) pain."
