HBO has released a second full-length trailer for Game of Thrones Season 4, and in it we get a few more clues about what we can expect from the new season.

Fans of the A Song of Ice and Fire book series have already been able to take a lot away from the first trailer and the extended Foreshadowing special, but this new promo gives us gives us some new things to chew on as we try to figure out exactly how the books are going to translate to the screen.

Here are the three biggest things we noticed.

Melisandre magic? At 0:36, there’s a brief scene of a fireball flying through the air. While it could be related to Dany’s dragons, of course, it could also be related to one of Melisandre’s more awesome scenes from the books. When the wildlings attack the Wall, Stannis’ army comes to the rescue, and during the fight Melisandre uses magic to cause Orell’s eagle (the one that scarred up Jon Snow’s face last season) to burst into flames. We have a feeling that’s what we’re seeing in this scene.

The end for Shae? Tyrion is going to be convicted of Joffrey’s murder, but while awaiting his sentence he’s going to be freed by Jaime. In the books, during his escape, Tyrion stops by Tywin’s chambers to murder him, but finds Shae in his father’s bed and murders her first. We were assuming the show would change this plot point, since the show version of Shae is a lot more sympathetic than the book version, but judging from the shot at 1:06 of Shae looking startled in a fancy bed, it looks like Season 4 may be her last. We hope this is still not what it seems, though. We can't imagine show Shae betraying Tyrion like that.

White Walkers! With all that’s going on in this show, it’s sometimes easy to forget that there’s a horde of supernatural monsters just beyond the Wall threatening everyone’s existence. The White Walker we see at 1:30 reminds us that they’re still there, and that they’ll be making an appearance in Season 4.
