Earlier this week, a brand new thirty-second trailer hit social media for the return of Freeform’s fantasy series Shadowhunters. The show has been on hiatus since its winter finale at the beginning of March and will air ten more episodes throughout the summer, with a Season 3 return slated for early 2018.

Though Freeform did release 2 ten-second teasers for Season 2B last week, they were both missing one highly-anticipated moment: the introduction of the show’s newest shadowhunter, Sebastian.

I know, I know — we probably, maybe, very briefly saw Sebastian for a hot second in the Season 2A finale when that mysterious cloaked figure walked away with the Soul Sword, but this is Shadowhunters we’re talking about. For all we know, it could have just been one of Valentine’s mutants who took the sword, right? (We’re not buying it either, but we’ll just have to wait and see…)

Sebastian is played by Will Tudor (Game of Thrones, Humans), and while fans who haven’t read The Mortal Instruments series might not know much about what’s in store for Sebastian this season, those who have already read the books exploded with feels at their first glimpse of Sebastian in action!

Seriously. He was only in the trailer for about 4 seconds, and he was trending WORLDWIDE for hours. The full quote, “My name is Sebastian,” earned close to 700,000 Twitter impressions, and that’s not including all of the tweets and retweets that used other tags or keywords.

In the clip, Sebastian infamously introduces himself with a dreamy British accent, heroically protects Isabelle by doing an over-the-top jump with his seraph blade (we love it), and maybe has some chemistry with Clary Fray?

Perhaps his moment with Izzy has something to do with why Raphael doesn’t trust him…

We already knew that Sebastian was going to be a fierce character and that Tudor was an amazing actor, but the way that the fandom rallied behind this trailer is making us even more excited/nervous for the Season 2B premiere!

Check out some of our favorite responses from fans after @ShadowhuntersTV dropped the trailer:

While we were surprised (and thrilled) to see that Sebastian’s moment in the trailer got so much attention, we also have a few other burning questions: Why is Alec caught off-guard on the floor in Magnus’ apartment with his quiver and arrows?! Why are the werewolves restraining Luke and who does Luke have in a choke hold?! Are Alec and Magnus hunting demons on the same mission with Izzy and Sebastian?! Are Simon, Clary and Jace headed to the Seelie Court?! And who’s the other woman in Magnus’ lair?!

Check back later this spring for an exclusive interview with Will Tudor and the rest of the Shadowhunters cast to learn more about Season 2B, premiering June 5th at 8pm on Freeform and on the Freeform App, and watch the trailer below to see the official introduction of Sebastian!
