A good friend of mine gave me the idea to fancast a Teen Wolf spin off, he did make one himself too: https://moviepilot.com/posts/2015/08/07/wolfs-in-london-fancast-2017-3449590?lt_source=external,manual Go check it out.

When Isaac runs into Jackson they get attacked, but after beating the werewolf Jackson kills him and turns into an Alpha. Isaac might need a pack and Jackson can't be alone, after some bad villains come into town Jackson needs a bigger pack. So he and Isaac find some boys that want to help.
