Game of Thrones star Will Tudor is set to play the enigmatic Sebastian at Shadowhunter set to shake things up on the Freeform show.

The last episode proved that the show and the books are set to diverge as Clary’s mother was killed.And things look to be getting a lot more different from the Mortal Instruments book series.

Joining the show in the second half of the second season, Will Tudor will be the second brit to join the cast after Dominic Sherwood, Tudor will also be using his native British accent as Sebastian will be coming from the London Shadowhunter’s Institute instead of the Parisian one.

Todd Slavkin, show runner explained the difference between show Sebastian and book Sebastian.

“We really put our own spin on him 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.”
