Will was just cast as Sebastian Verlac for the popular Freeform series. He turns out to be the older brother of Clary. As a result of experiments done on him by his father, Sebastian is a Shadowhunter born with demon blood.
But instead of being from the Paris Institute as he is in the books, he’ll be from London this time around.
“We really put our own spin on him the character,” showrunner Todd Slavkin shared with TVLine about the character. “As we’ve done with all the episodes you’ve seen, we’ve always had our own spin on everything, and Sebastian is no different.”
A fun note from the interview: Will and star Dominic Sherwood are longtime friends!
Todd shared, “We weren’t aware of this when we cast him, but he and Dominic Sherwood have this past together as kids in England. They have this real friendship off-screen, which is chilling if you know the books and can think about the irony of that.”
