I think this is the last episode of Shadowhunters that I’m forcing myself through.
Once again, we fly through story arcs and subplots. We are introduced to Magnus Bane’s old friend Ragnar Fell on the off-chance he might know how to awaken Clary’s mom from the weird potion induced coma that she is currently floating in. I think his total screen time takes up 5 minutes. His total arc follows Shadowhunters trademark, go find, finish formula: Clary and Co. find his home, make their ways through his wards, he drops “Book of the White” as a plot point and then gets killed.
Why even introduce him? The same information could have been given to us in a note. There was nothing special except to say there are other warlocks.
