Shadowhunters made their debut at Wondercon 2016 and the cast were nothing but grateful to the fans that support the series. Freeform even treated the fans to a teaser of Alec Lightwood’s wedding where an unexpected guest crashes the wedding. I am sure you know who! If not the clip of the wedding scene is down below for those looking to be spoiled before the episode airs on Tuesday at 8:00 pm on Freeform! Enjoy!
