The summer finale of “Teen Wolf” was pretty epic. Here’s a quick cheat sheet of what you need to know going into Season 3b.

--Deucalion (Gideon Emery) has his eyesight back after the Darach/Jennifer (Haley Webb) healed him

--Scott (Tyler Posey) is now a true Alpha

--Scott’s father/FBI Agent McCall (Matthew Del Negro) is back which Scott isn’t particularly thrilled about.

--Issac (Daniel Sharman) and Allison (Crystal Reed) continue to get closer—maybe a relationship is brewing there

--Derek (Tyler Hoechlin) is now a beta but at least his sister Cora (Adelaide Kane) is alive

--Deucalion slits Jennifer’s throat. She crawls to the nemeton to once again get help and, unfortunately for her she runs into Uncle Peter (Ian Bohen) who is apparently up to his old tricks. The final scene of Season 3a shows Peter standing over a weak Jennifer and—after finishing her off—he yells, “I am the Alpha. I’VE ALWAYS BEEN THE ALPHA!!!!!!!!!!!!”

As we head into Season 3b, Scott and his friends are going to get two new allies—Ethan (Charlie Carver) and Aiden (Max Carver).

Show creator and executive producer Jeff Davis recently said the twins’ transfer to the good side might make things a bit weird.

"Things definitely get complicated between Aiden and Lydia because we've taken the twins from bad guys to good guys and that's a lot to live up to for them,” he said according to EOnline.com. “They've got a lot to prove."

Oh and as for Stiles (Dylan O’Brien) and Lydia (Holland Roden) getting together he said, there’s always hope.”

Season 3b of Teen Wolf will premiere Jan. 6 on MTV.
