'Game of Thrones' Fans Are Freaking Out After Seeing a Familiar Face in 'Stranger Things' Season 4 Teaser

The latest teaser for Season 4 of Stranger Things dropped one week ago and now we have so many reasons to be excited. Firstly--and most obviously--Jim Hopper (played by David Harbour) is still alive! And now, people are realizing (in part thanks from a tweet from the official Twitter account) that Game of Thrones followers have a big reason to celebrate, thanks to the sighting of a new cast member.

Remember the 'Faceless Man,' a.k.a. Jaqen H’ghar? He trained Arya Stark in Braavos to also become a Faceless Man. Well, he wasn't so faceless this time around and fans quickly recognized actor Tom Wlaschiha in the teaser. It appears he is playing a Russian soldier and a guard to Hopper. He's definitely looking a little different, with shorter hair and a mustache. See below.

Twitter users have been expressing their excitement over the Thrones actor's appearance, with one writing, "VALAR MORGHULIS, B***HES!!!!!!!," and another adding, "OMG CHILL THAT[']S THE GOT GUY???"

The Game of Thrones cast has begun popping up in all new places now that the HBO epic series has concluded. For instance, Nathalie Emmanuel, who played the interpreter and close friend to Daenerys Targaryen, Missandei, has been cast in a new Quibi series alongside Kevin Hart called Die Hart. Sophie Turner, who of course played Sansa Stark, is also starring in an upcoming Quibi show called Survive.

While there's no confirmed release date for Stranger Things Season 4 yet, we're so excited for what (and who) is to come.
