Shadowhunters S2 E212 Extended Trailer: "You Are Not Your Own"

Who's watching Shadowhunters tonight? I can't wait to see this episode because poor Magnus, he's trying to get everyone to believe that he's really not Valentine. And unless Harry Shum, Jr. is leaving the show then I'm sure someone will stop or delay the execution so they can find out the truth.

I hope that Alec will at least notice if "Magnus" is acting strange or appears different and also not to trust Jace's bad advice. It looks like it will be a good episode.
