Speaking of Quentin and Alice, when last we left them she was pretty pissed off that he slept with Eliot and Margo (yea, both of them, at the same time - you read that right).
By the by, it's worth noting here that Quentin is now KING OF FILLORY. This is the guy that's been obsessed with this land since he was pre-pubescent. And now he's a ruler.
Speaking of Penny, he doesn't get the royal treatment in Fillory but don't think he's not a big player this season. In particular, look for developments in his relationship with....
Ah, The Beast - the big bad that seemingly killed all our main players at the end of last season (spoiler alert: They're not dead. Duh). He better watch his back, because Alice is coming for him.
So Eliot. He's in an arranged marriage with Fen (remember, he did it to give the gang a means to fight The Beast?). Also, he's a king now. This is not an uncomplicated situation.
Dean Fogg is back too! Don't think Brakebills University is going away. It's got a big presence in Season 2 - and we learn some interesting stuff about the Dean's past.
