Magnus and Blackfriars bridge.
So Magnus I have written about before is a very complex character both in the books and in the show. He is the son of a demon and a prince of hell. He can perform complex magic as is seen as a threat by the other warlocks, because of his power's. In the books he has a different life story to the show and there was a want from the actor that played Magnus to explore the charcters backstory and how this is amazing for the show if it was to be continued, in various ways. ( This being Harry Shum jr) Magnus being a very complex character in the books we don't seem to see much of in the show his powers but one thing is that his realtionship with mental health is an interesting one to look at as, he is immortal. Yet this isn't over stated in the show, it is mentioned in two seems in the show that he has had struggles with mental health. We see him as a very hedonist character and this changes when he meets Alec as he has a purpose in life again. He has an anchor to guide him.
