Most Memorable Scene: Shadowhunters Opening Scene

I don't know, I just love the opening scene in the Shadowhunters season 1 first episode The Mortal Cup. It's just so dramatic with Alexander "Alec" Lightwood, his sister Isabelle "Izzy" Lightwood and their brother Jace Wayland tracking a shapeshifter (or possible demon, it's been a while since I've watched the show). Anyway, they didn't have to do half of the things they did to keep eye on the shapeshifter. Which includes the coordinated backward flips down to the ground.

Yes, I just love it. It's all so over the top especially when they are basically invisible to humans due to the use of one of their magical tattoos (or runes). Which is why it was all surprising and dramatic that Clary Fray was able to see Jace after he bumped into her. But back to them being invisible, none of the things they did were necessary especially since no one except for the shapeshifter (who wasn't really paying attention) to notice them. Which is why all of this during the opening scene just makes this so memorable.
